  • Data-Driven Neural Network Model for Robust Reconstruction of Automobile
           Casting
    • Authors: Jinhua Lin; Yanjie Wang; Xin Li; Lu Wang
      Abstract: In computer vision system, it is a challenging task to robustly reconstruct complex 3D geometries of automobile castings. However, 3D scanning data is usually interfered by noises, the scanning resolution is low, these effects normally lead to incomplete matching and drift phenomenon. In order to solve these problems, a data-driven local geometric learning model is proposed to achieve robust reconstruction of automobile casting. In order to relieve the interference of sensor noise and to be compatible with incomplete scanning data, a 3D convolution neural network is established to match the local geometric features of automobile casting. The proposed neural network combines the geometric feature representation with the correlation metric function to robustly match the local correspondence. We use the truncated distance field(TDF) around the key point to represent the 3D surface of casting geometry, so that the model can be directly embedded into the 3D space to learn the geometric feature representation; Finally, the training labels is automatically generated for depth learning based on the existing RGB-D reconstruction algorithm, which accesses to the same global key matching descriptor. The experimental results show that the matching accuracy of our network is 92.2% for automobile castings, the closed loop rate is about 74.0% when the matching tolerance threshold τ is 0.2. The matching descriptors performed well and retained 81.6% matching accuracy at 95% closed loop. For the sparse geometric castings with initial matching failure, the 3D matching object can be reconstructed robustly by training the key descriptors. Our method performs 3D reconstruction robustly for complex automobile castings.

  • Content-Based Image Retrieval Based on Shape Similarity Calculation
    • Authors: Cong Jin; Shan-Wu Ke
      Abstract: In the content-based image retrieval technology, the performance of retrieval system using only a single image feature is generally unsatisfactory, and therefore the image retrieval system using two or more image features is more often used. When there is the target deformation or the size variation, the performance of image retrieval system using only shape features is not satisfactory, too. To solve these problems, in this paper, the extraction of image salient region and a shape representation methods of describing the image content are proposed, then they are used with image texture and color features to implement image retrieval. Experimental results show that the proposed image retrieval system can provide very good retrieval performance.

  • A New Parametric Kernel Estimation Technique for License Plate Image
           De-blurring
    • Authors: P. S. Prashanth Rao; Rajesh Kumar Muthu
      Abstract: A recognizable license plate in a picture taken by a traffic monitoring system is crucial for identifying the vehicles involved in traffic violations. In the image of a vehicle taken by a surveillance camera, the license plate is often blurred due to fast motion and cannot be recognized by the human eye. In this type of blurring, the blur kernel can be seen to be a linear uniform convolution parametrically described by its angle and length. In this paper, we introduce a new estimation technique to determine this kernel accurately in order to improve our de-blurred result. We use the Hough transform in estimating the direction in which the image is blurred. To determine the extent of the blur in that direction, we employ a new method involving the cepstrum of the blurred image. We compare the performance of our method to that of other recent blind de-blurring techniques. These comparisons show that our proposed scheme can handle significant blur in the captured image to give a good output image.

  • Registration of Visible and Infrared Images Based on Gradient Information
    • Authors: Yingnan Geng; Yanan Wang
      Abstract: Multi-modality image registration is very challenging due to disparate imaging theory of sensors. Extraction of similar features and evaluation of algorithms have been two key difficulties. In this paper, gradient of RGB vector space, as a similar image feature, is shown the viability of using for the registration of infrared and visible still stereo pairs. Based on adaptive support-window algorithm, a novel method, which formulates the registration problem as correspondences between gradients of RGB vector space and obtains the best matching by minimizing gradient difference in sliding correspondence support-windows, is proposed. Evaluation experiments demonstrate high rates of successful registration by yielding qualitative and quantitative results. Graphical

  • Efficient 3D Watermarked Video Communication with Chaotic Interleaving,
           Convolution Coding, and LMMSE Equalization
    • Authors: W. El-Shafai; E. M. El-Bakary; S. El-Rabaie; O. Zahran; M. El-Halawany; F. E. Abd El-Samie
      Abstract: Three-Dimensional Multi-View Video (3D-MVV) transmission over wireless networks suffers from Macro-Blocks losses due to either packet dropping or fading-motivated bit errors. Thus, the robust performance of 3D-MVV transmission schemes over wireless channels becomes a recent considerable hot research issue due to the restricted resources and the presence of severe channel errors. The 3D-MVV is composed of multiple video streams shot by several cameras around a single object, simultaneously. Therefore, it is an urgent task to achieve high compression ratios to meet future bandwidth constraints. Unfortunately, the highly-compressed 3D-MVV data becomes more sensitive and vulnerable to packet losses, especially in the case of heavy channel faults. Thus, in this paper, we suggest the application of a chaotic Baker interleaving approach with equalization and convolution coding for efficient Singular Value Decomposition (SVD) watermarked 3D-MVV transmission over an Orthogonal Frequency Division Multiplexing wireless system. Rayleigh fading and Additive White Gaussian Noise are considered in the real scenario of 3D-MVV transmission. The SVD watermarked 3D-MVV frames are primarily converted to their luminance and chrominance components, which are then converted to binary data format. After that, chaotic interleaving is applied prior to the modulation process. It is used to reduce the channel effects on the transmitted bit streams and it also adds a degree of encryption to the transmitted 3D-MVV frames. To test the performance of the proposed framework; several simulation experiments on different SVD watermarked 3D-MVV frames have been executed. The experimental results show that the received SVD watermarked 3D-MVV frames still have high Peak Signal-to-Noise Ratios and watermark extraction is possible in the proposed framework. Graphical

  • Performance-Driven Hybrid Full-Body Character Control for Navigation and
           Interaction in Virtual Environments
    • Authors: Christos Mousas; Christos-Nikolaos Anagnostopoulos
      Abstract: This paper presents a hybrid character control interface that provides the ability to synthesize in real-time a variety of actions based on the user’s performance capture. The proposed methodology enables three different performance interaction modules: the performance animation control that enables the direct mapping of the user’s pose to the character, the motion controller that synthesizes the desired motion of the character based on an activity recognition methodology, and the hybrid control that lies within the performance animation and the motion controller. With the methodology presented, the user will have the freedom to interact within the virtual environment, as well as the ability to manipulate the character and to synthesize a variety of actions that cannot be performed directly by him/her, but which the system synthesizes. Therefore, the user is able to interact with the virtual environment in a more sophisticated fashion. This paper presents examples of different scenarios based on the three different full-body character control methodologies.

  • Quantitative Anthropometric Measures of Facial Appearance of Healthy
           Hispanic/Latino White Children: Establishing Reference Data for Care of
           Cleft Lip With or Without Cleft Palate
    • Authors: Juhun Lee; Brian Ku; Patrick D. Combs; Adriana. C. Da Silveira; Mia K. Markey
      Abstract: Cleft lip with or without cleft palate (CL ± P) is one of the most common congenital facial deformities worldwide. To minimize negative social consequences of CL ± P, reconstructive surgery is conducted to modify the face to a more normal appearance. Each race/ethnic group requires its own facial norm data, yet there are no existing facial norm data for Hispanic/Latino White children. The objective of this paper is to identify measures of facial appearance relevant for planning reconstructive surgery for CL ± P of Hispanic/Latino White children. Quantitative analysis was conducted on 3D facial images of 82 (41 girls, 41 boys) healthy Hispanic/Latino White children whose ages ranged from 7 to 12 years. Twenty-eight facial anthropometric features related to CL ± P (mainly in the nasal and mouth area) were measured from 3D facial images. In addition, facial aesthetic ratings were obtained from 16 non-clinical observers for the same 3D facial images using a 7-point Likert scale. Pearson correlation analysis was conducted to find features that were correlated with the panel ratings of observers. Boys with a longer face and nose, or thicker upper and lower lips are considered more attractive than others while girls with a less curved middle face contour are considered more attractive than others. Associated facial landmarks for these features are primary focus areas for reconstructive surgery for CL ± P. This study identified anthropometric measures of facial features of Hispanic/Latino White children that are pertinent to CL ± P and which correlate with the panel attractiveness ratings.

  • A Hierarchical Optimization Algorithm Based on GPU for Real-Time 3D
           Reconstruction
    • Authors: Jin-hua Lin; Lu Wang; Yan-jie Wang
      Abstract: In machine vision sensing system, it is important to realize high-quality real-time 3D reconstruction in large-scale scene. The recent online approach performed well, but scaling up the reconstruction, it causes pose estimation drift, resulting in the cumulative error, usually requiring a large number of off-line operation to completely correct the error, reducing the reconstruction performance. In order to optimize the traditional volume fusion method and improve the old frame-to-frame pose estimation strategy, this paper presents a real-time CPU to Graphic Processing Unit reconstruction system. Based on a robust camera pose estimation strategy, the algorithm fuses all the RGB-D input values into an effective hierarchical optimization framework, and optimizes each frame according to the global camera attitude, eliminating the serious dependence on the tracking timeliness and continuously tracking globally optimized frames. The system estimates the global optimization of gestures (bundling) in real-time, supports for robust tracking recovery (re-positioning), and re-estimation of large-scale 3D scenes to ensure global consistency. It uses a set of sparse corresponding features, geometric and ray matching functions in one of the parallel optimization systems. The experimental results show that the average reconstruction time is 415 ms per frame, the ICP pose is estimated 20 times in 100.0 ms. For large scale 3D reconstruction scene, the system performs well in online reconstruction area, keeping the reconstruction accuracy at the same time. Graphical

    • Authors: Ming Xu
      Abstract: Recently, chaotic image cipher using DNA sequence operation has been studied extensively. However, corresponding cryptanalysis is lacking, which impedes its further development. This paper cryptanalyzes a newly proposed chaotic image cipher based on DNA sequence operation. In this paper, we firstly analyze the security defects of the proposal. Then by applying chosen-plaintext attack, we show that all the secret parameters can be revealed. The effectiveness of the proposed chosen-plaintext attack is supported both by rigorous theoretical analysis and experimental results. Graphical

  • Saliency Detection of Stereoscopic 3D Images with Application to Visual
           Discomfort Prediction
    • Authors: Hong Li; Ting Luo; Haiyong Xu
      Abstract: Visual saliency detection is potentially useful for a wide range of applications in image processing and computer vision fields. This paper proposes a novel bottom-up saliency detection approach for stereoscopic 3D (S3D) images based on regional covariance matrix. As for S3D saliency detection, besides the traditional 2D low-level visual features, additional 3D depth features should also be considered. However, only limited efforts have been made to investigate how different features (e.g. 2D and 3D features) contribute to the overall saliency of S3D images. The main contribution of this paper is that we introduce a nonlinear feature integration descriptor, i.e., regional covariance matrix, to fuse both 2D and 3D features for S3D saliency detection. The regional covariance matrix is shown to be effective for nonlinear feature integration by modelling the inter-correlation of different feature dimensions. Experimental results demonstrate that the proposed approach outperforms several existing relevant models including 2D extended and pure 3D saliency models. In addition, we also experimentally verified that the proposed S3D saliency map can significantly improve the prediction accuracy of experienced visual discomfort when viewing S3D images.

  • A Simple Secure Hash Function Scheme Using Multiple Chaotic Maps
    • Authors: Musheer Ahmad; Shruti Khurana; Sushmita Singh; Hamed D. AlSharari
      Abstract: The chaotic maps posses high parameter sensitivity, random-like behavior and one-way computations, which favor the construction of cryptographic hash functions. In this paper, we propose to present a novel hash function scheme which uses multiple chaotic maps to generate efficient variable-sized hash functions. The message is divided into four parts, each part is processed by a different 1D chaotic map unit yielding intermediate hash code. The four codes are concatenated to two blocks, then each block is processed through 2D chaotic map unit separately. The final hash value is generated by combining the two partial hash codes. The simulation analyses such as distribution of hashes, statistical properties of confusion and diffusion, message and key sensitivity, collision resistance and flexibility are performed. The results reveal that the proposed anticipated hash scheme is simple, efficient and holds comparable capabilities when compared with some recent chaos-based hash algorithms.

  • A Group Action Method for Construction of Strong Substitution Box
    • Authors: Sajjad Shaukat Jamal; Tariq Shah; Atta Attaullah
      Abstract: In this paper, the method to develop cryptographically strong substitution box is presented which can be used in multimedia security and data hiding techniques. The algorithm of construction depends on the action of a projective general linear group over the set of units of the finite commutative ring. The strength of substitution box and ability to create confusion is assessed with different available analyses. Moreover, the ability of resistance against malicious attacks is also evaluated. The substitution box is examined by bit independent criterion, strict avalanche criterion, nonlinearity test, linear approximation probability test and differential approximation probability test. This substitution box is equated with well-recognized substitution boxes such as AES, Gray, APA, S8, prime of residue, Xyi and Skipjack. The comparison shows encouraging results about the strength of the proposed box. The majority logic criterion is also calculated to analyze the strength and its practical implementation.

  • On the Uncertain Future of the Volumetric 3D Display Paradigm
    • Authors: Barry G. Blundell
      Abstract: Volumetric displays permit electronically processed images to be depicted within a transparent physical volume and enable a range of cues to depth to be inherently associated with image content. Further, images can be viewed directly by multiple simultaneous observers who are able to change vantage positions in a natural way. On the basis of research to date, we assume that the technologies needed to implement useful volumetric displays able to support translucent image formation are available. Consequently, in this paper we review aspects of the volumetric paradigm and identify important issues which have, to date, precluded their successful commercialization. Potentially advantageous characteristics are outlined and demonstrate that significant research is still needed in order to overcome barriers which continue to hamper the effective exploitation of this display modality. Given the recent resurgence of interest in developing commercially viable general purpose volumetric systems, this discussion is of particular relevance.

  • An Information Perception-Based Emotion Contagion Model for Fire
           Evacuation
    • Authors: Ting Ting Liu; Zhen Liu; Minhua Ma; Rongrong Xuan; Tian Chen; Tao Lu; Lipeng Yu
      Abstract: In fires, people are easier to lose their mind. Panic will lead to irrational behavior and irreparable tragedy. It has great practical significance to make contingency plans for crowd evacuation in fires. However, existing studies about crowd simulation always paid much attention on the crowd density, but little attention on emotional contagion that may cause a panic. Based on settings about information space and information sharing, this paper proposes an emotional contagion model for crowd in panic situations. With the proposed model, a behavior mechanism is constructed for agents in the crowd and a prototype of system is developed for crowd simulation. Experiments are carried out to verify the proposed model. The results showed that the spread of panic not only related to the crowd density and the individual comfort level, but also related to people’s prior knowledge of fire evacuation. The model provides a new way for safety education and evacuation management. It is possible to avoid and reduce unsafe factors in the crowd with the lowest cost.

  • Designing S-Box Based on 4D-4Wing Hyperchaotic System
    • Authors: Faiz ul Islam; Guangjie Liu
      Abstract: S-box plays an imperative role in designing a cryptographically strong block cipher. Designing S-box based on chaos has attracted lots of attentions because of its distinct characteristics relevant to cryptography. In this paper, a 4D-4wing hyperchaotic system is investigated. Its sophisticated nonlinear behaviors are used to generate two pseudorandom 8-bit integer sequences, which further drive iterative two-position swap on the identical map on GF(28). According to the indicator of typical evaluation criteria including nonlinearity, differential uniformity, strict avalanche criterion, output bits independence criterion and bijective property, the preferred S-box is obtained from all those batch-generated ones. The comparison with the state-of-the-art chaos-based schemes shows that the obtained S-box achieves better cryptographical performance.

  • Replacement Attack: A New Zero Text Watermarking Attack
    • Authors: Morteza Bashardoost; Mohd Shafry Mohd Rahim; Tanzila Saba; Amjad Rehman
      Abstract: The main objective of zero watermarking methods that are suggested for the authentication of textual properties is to increase the fragility of produced watermarks against tampering attacks. On the other hand, zero watermarking attacks intend to alter the contents of document without changing the watermark. In this paper, the Replacement attack is proposed, which focuses on maintaining the location of the words in the document. The proposed text watermarking attack is specifically effective on watermarking approaches that exploit words’ transition in the document. The evaluation outcomes prove that tested word-based method are unable to detect the existence of replacement attack in the document. Moreover, the comparison results show that the size of Replacement attack is estimated less accurate than other common types of zero text watermarking attacks.

  • Robust Reconstruction and Generalized Dual Hahn Moments Invariants
           Extraction for 3D Images
    • Authors: Abderrahim Mesbah; Amal Zouhri; Mostafa El Mallahi; Khalid Zenkouar; Hassan Qjidaa
      Abstract: In this paper, we introduce a new set of 3D weighed dual Hahn moments which are orthogonal on a non-uniform lattice and their polynomials are numerically stable to scale, consequent, producing a set of weighted orthonormal polynomials. The dual Hahn is the general case of Tchebichef and Krawtchouk, and the orthogonality of dual Hahn moments eliminates the numerical approximations. The computational aspects and symmetry property of 3D weighed dual Hahn moments are discussed in details. To solve their inability to invariability of large 3D images, which cause to overflow issues, a generalized version of these moments noted 3D generalized weighed dual Hahn moment invariants are presented where whose as linear combination of regular geometric moments. For 3D pattern recognition, a generalized expression of 3D weighted dual Hahn moment invariants, under translation, scaling and rotation transformations, have been proposed where a new set of 3D-GWDHMIs have been provided. In experimental studies, the local and global capability of free and noisy 3D image reconstruction of the 3D-WDHMs has been compared with other orthogonal moments such as 3D Tchebichef and 3D Krawtchouk moments using Princeton Shape Benchmark database. On pattern recognition using the 3D-GWDHMIs like 3D object descriptors, the experimental results confirm that the proposed algorithm is more robust than other orthogonal moments for pattern classification of 3D images with and without noise.

  • A Feature-adaptive Subdivision Method for Real-time 3D Reconstruction of
           Repeated Topology Surfaces
    • Authors: Jinhua Lin; Yanjie Wang; Honghai Sun
      Abstract: It’s well known that rendering for a large number of triangles with GPU hardware tessellation has made great progress. However, due to the fixed nature of GPU pipeline, many off-line methods that perform well can not meet the on-line requirements. In this paper, an optimized Feature-adaptive subdivision method is proposed, which is more suitable for reconstructing surfaces with repeated cusps or creases. An Octree primitive is established in irregular regions where there are the same sharp vertices or creases, this method can find the neighbor geometry information quickly. Because of having the same topology structure between Octree primitive and feature region, the Octree feature points can match the arbitrary vertices in feature region more precisely. In the meanwhile, the patches is re-encoded in the Octree primitive by using the breadth-first strategy, resulting in a meta-table which allows for real-time reconstruction by GPU hardware tessellation unit. There is only one feature region needed to be calculated under Octree primitive, other regions with the same repeated feature generate their own meta-table directly, the reconstruction time is saved greatly for this step. With regard to the meshes having a large number of repeated topology feature, our algorithm improves the subdivision time by 17.575% and increases the average frame drawing time by 0.2373 ms compared to the traditional FAS (Feature-adaptive Subdivision), at the same time the model can be reconstructed in a watertight manner.

  • DCT and DST Based Image Compression for 3D Reconstruction
    • Authors: Mohammed M. Siddeq; Marcos A. Rodrigues
      Abstract: This paper introduces a new method for 2D image compression whose quality is demonstrated through accurate 3D reconstruction using structured light techniques and 3D reconstruction from multiple viewpoints. The method is based on two discrete transforms: (1) A one-dimensional Discrete Cosine Transform (DCT) is applied to each row of the image. (2) The output from the previous step is transformed again by a one-dimensional Discrete Sine Transform (DST), which is applied to each column of data generating new sets of high-frequency components followed by quantization of the higher frequencies. The output is then divided into two parts where the low-frequency components are compressed by arithmetic coding and the high frequency ones by an efficient minimization encoding algorithm. At decompression stage, a binary search algorithm is used to recover the original high frequency components. The technique is demonstrated by compressing 2D images up to 99% compression ratio. The decompressed images, which include images with structured light patterns for 3D reconstruction and from multiple viewpoints, are of high perceptual quality yielding accurate 3D reconstruction. Perceptual assessment and objective quality of compression are compared with JPEG and JPEG2000 through 2D and 3D RMSE. Results show that the proposed compression method is superior to both JPEG and JPEG2000 concerning 3D reconstruction, and with equivalent perceptual quality to JPEG2000.
