  • An Effective Construction Method of Modular Manipulator 3D Virtual
           Simulation Platform
    • Authors: Xianhua Li; Lei Lv; Rui Sheng; Qing Sun; Leigang Zhang
      Abstract: This work discusses about a fast and efficient method of constructing an open 3D manipulator virtual simulation platform which make it easier for teachers and students to learn about positive and inverse kinematics of a robot manipulator. The method was carried out using MATLAB. In which, the Robotics Toolbox, MATLAB GUI and 3D animation with the help of modelling using SolidWorks, were fully applied to produce a good visualization of the system. The advantages of using quickly build is its powerful function of the input and output and its ability to simulate a 3D manipulator realistically. In this article, a Schunk six DOF modular manipulator was constructed by the author’s research group to be used as example. The implementation steps of this method was detailed described, and thereafter, a high-level open and realistic visualization manipulator 3D virtual simulation platform was achieved. With the graphs obtained from simulation, the test results show that the manipulator 3D virtual simulation platform can be constructed quickly with good usability and high maneuverability, and it can meet the needs of scientific research and teaching.

  • Multi-phase Fluid Simulation Based on Narrow-Band FLIP Method
    • Authors: Changjun Zou; Yong Yin
      Abstract: Euler method and Lagrangian method is applicable for fluid of different deformation respectively. The fluid implicit particle (FLIP) method is a combination of Euler method and Lagrangian method which embodies the advantages of both in fluid simulation. While narrow-band FLIP (NBFLIP) method is an improved FLIP method which limits the particles within the Narrow Band near the interface. NBFLIP method improves the computational efficiency by eliminating particle outside the Narrow Band without degrading the details. In this paper, the multi-phase volume of fraction (VOF) model based on NBFLIP (NBFLIP-VOF) method is proposed. This is the first combination of multi-phase VOF model with NBFLIP method. The method employees a unified framework to deal with miscible and immiscible fluid simulation, the simulation results are highly consistent with the results from previous literature. The results show that the NBFLIP-VOF method has a good performance in the simulation of multi-phase flow, it also proves the reliability of the method and the adaptability in multi-phase fluid simulation.

  • Template-Based 3D Reconstruction of Non-rigid Deformable Object from
           Monocular Video
    • Authors: Yang Liu; Xiaodong Peng; Wugen Zhou; Bo Liu; Andreas Gerndt
      Abstract: In this paper, we propose a template-based 3D surface reconstruction system of non-rigid deformable objects from monocular video sequence. Firstly, we generate a semi-dense template of the target object with structure from motion method using a subsequence video. This video can be captured by rigid moving camera orienting the static target object or by a static camera observing the rigid moving target object. Then, with the reference template mesh as input and based on the framework of classical template-based methods, we solve an energy minimization problem to get the correspondence between the template and every frame to get the time-varying mesh to present the deformation of objects. The energy terms combine photometric cost, temporal and spatial smoothness cost as well as as-rigid-as-possible cost which can enable elastic deformation. In this paper, an easy and controllable solution to generate the semi-dense template for complex objects is presented. Besides, we use an effective iterative Schur based linear solver for the energy minimization problem. The experimental evaluation presents qualitative deformation objects reconstruction results with real sequences. Compare against the results with other templates as input, the reconstructions based on our template have more accurate and detailed results for certain regions. The experimental results show that the linear solver we used performs better efficiency compared to traditional conjugate gradient based solver.

  • Optical Double Image Hiding in the Fractional Hartley Transform Using
           Structured Phase Filter and Arnold Transform
    • Authors: Poonam Lata Yadav; Hukum Singh
      Abstract: To maintain the security of the image encryption and to protect the image from intruders, a new asymmetric cryptosystem based on fractional Hartley Transform (FrHT) and the Arnold transform (AT) is proposed. AT is a method of image cropping and edging in which pixels of the image are reorganized. In this cryptosystem we have used AT so as to extent the information content of the two original images onto the encrypted images so as to increase the safety of the encoded images. We have even used Structured Phase Mask (SPM) and Hybrid Mask (HM) as the encryption keys. The original image is first multiplied with the SPM and HM and then transformed with direct and inverse fractional Hartley transform so as to obtain the encrypted image. The fractional orders of the FrHT and the parameters of the AT correspond to the keys of encryption and decryption methods. If both the keys are correctly used only then the original image would be retrieved. Recommended method helps in strengthening the safety of DRPE by growing the key space and the number of parameters and the method is robust against various attacks. By using MATLAB (R2014a) we calculate the strength of the recommended cryptosystem. A set of simulated results shows the power of the proposed asymmetric cryptosystem.

  • Saliency Detection for Stereoscopic 3D Images in the Quaternion Frequency
    • Authors: Xingyu Cai; Wujie Zhou; Gang Cen; Weiwei Qiu
      Abstract: Recent studies have shown that a remarkable distinction exists between human binocular and monocular viewing behaviors. Compared with two-dimensional (2D) saliency detection models, stereoscopic three-dimensional (S3D) image saliency detection is a more challenging task. In this paper, we propose a saliency detection model for S3D images. The final saliency map of this model is constructed from the local quaternion Fourier transform (QFT) sparse feature and global QFT log-Gabor feature. More specifically, the local QFT feature measures the saliency map of an S3D image by analyzing the location of a similar patch. The similar patch is chosen using a sparse representation method. The global saliency map is generated by applying the wake edge-enhanced gradient QFT map through a band-pass filter. The results of experiments on two public datasets show that the proposed model outperforms existing computational saliency models for estimating S3D image saliency.

  • Entropy Based Feature Selection for Fuzzy Set-Valued Information Systems
    • Authors: Waseem Ahmed; M. M. Sufyan Beg; Tanvir Ahmad
      Abstract: In Set-valued Information Systems (SIS), several objects contain more than one value for some attributes. Tolerance relation used for handling SIS sometimes leads to loss of certain information. To surmount this problem, fuzzy rough model was introduced. However, in some cases, SIS may contain some real or continuous set-values. Therefore, the existing fuzzy rough model for handling Information system with fuzzy set-values needs some changes. In this paper, Fuzzy Set-valued Information System (FSIS) is proposed and fuzzy similarity relation for FSIS is defined. Yager’s relative conditional entropy was studied to find the significance measure of a candidate attribute of FSIS. Later, using these significance values, three greedy forward algorithms are discussed for finding the reduct and relative reduct for the proposed FSIS. An experiment was conducted on a sample population of the real dataset and a comparison of classification accuracies of the proposed FSIS with the existing SIS and single-valued Fuzzy Information Systems was made, which demonstrated the effectiveness of proposed FSIS.

  • Gaussian Radial Basis Function for Efficient Computation of Forest
           Indirect Illumination
    • Authors: Fayçal Abbas; Mohamed Chaouki Babahenini
      Abstract: Global illumination of natural scenes in real time like forests is one of the most complex problems to solve, because the multiple inter-reflections between the light and material of the objects composing the scene. The major problem that arises is the problem of visibility computation. In fact, the computing of visibility is carried out for all the set of leaves visible from the center of a given leaf, given the enormous number of leaves present in a tree, this computation performed for each leaf of the tree which also reduces performance. We describe a new approach that approximates visibility queries, which precede in two steps. The first step is to generate point cloud representing the foliage. We assume that the point cloud is composed of two classes (visible, not-visible) non-linearly separable. The second step is to perform a point cloud classification by applying the Gaussian radial basis function, which measures the similarity in term of distance between each leaf and a landmark leaf. It allows approximating the visibility requests to extract the leaves that will be used to calculate the amount of indirect illumination exchanged between neighbor leaves. Our approach allows efficiently treat the light exchanges in the scene of a forest, it allows a fast computation and produces images of good visual quality, all this takes advantage of the immense power of computation of the GPU.

    • Authors: Hamidreza Kakaei Kate; Jafar Razmara; Ayaz Isazadeh
      Abstract: Today, in the world of information communication, voice information has a particular importance. One way to preserve voice data from attacks is voice encryption. The encryption algorithms use various techniques such as hashing, chaotic, mixing, and many others. In this paper, an algorithm is proposed for voice encryption based on three different schemes to increase flexibility and strength of the algorithm. The proposed algorithm uses an innovative encoding scheme, the DNA encryption technique and a permutation function to provide a secure and fast solution for voice encryption. The algorithm is evaluated based on various measures including signal to noise ratio, peak signal to noise ratio, correlation coefficient, signal similarity and signal frequency content. The results demonstrate applicability of the proposed method in secure and fast encryption of voice files. Graphical

  • Specialized Computer Systems for Environment Visualization
    • Authors: Anas M. Al-Oraiqat; Evgeniy A. Bashkov; Sergii A. Zori
      Abstract: The need for real time image generation of landscapes arises in various fields as part of tasks solved by virtual and augmented reality systems, as well as geographic information systems. Such systems provide opportunities for collecting, storing, analyzing and graphically visualizing geographic data. Algorithmic and hardware software tools for increasing the realism and efficiency of the environment visualization in 3D visualization systems are proposed. This paper discusses a modified path tracing algorithm with a two-level hierarchy of bounding volumes and finding intersections with Axis-Aligned Bounding Box. The proposed algorithm eliminates the branching and hence makes the algorithm more suitable to be implemented on the multi-threaded CPU and GPU. A modified ROAM algorithm is used to solve the qualitative visualization of reliefs’ problems and landscapes. The algorithm is implemented on parallel systems—cluster and Compute Unified Device Architecture-networks. Results show that the implementation on MPI clusters is more efficient than Graphics Processing Unit/Graphics Processing Clusters and allows real-time synthesis. The organization and algorithms of the parallel GPU system for the 3D pseudo stereo image/video synthesis are proposed. With realizing possibility analysis on a parallel GPU-architecture of each stage, 3D pseudo stereo synthesis is performed. An experimental prototype of a specialized hardware-software system 3D pseudo stereo imaging and video was developed on the CPU/GPU. The experimental results show that the proposed adaptation of 3D pseudo stereo imaging to the architecture of GPU-systems is efficient. Also it accelerates the computational procedures of 3D pseudo-stereo synthesis for the anaglyph and anamorphic formats of the 3D stereo frame without performing optimization procedures. The acceleration is on average 11 and 54 times for test GPUs.

  • Enhancing Security of Double Random Phase Encoding Based on Random S-Box
    • Authors: R. Girija; Hukum Singh
      Abstract: In this paper, we propose a novel asymmetric cryptosystem for double random phase encoding (DRPE) using random S-Box. While utilising S-Box separately is not reliable and DRPE does not support non-linearity, so, our system unites the effectiveness of S-Box with an asymmetric system of DRPE (through Fourier transform). The uniqueness of proposed cryptosystem lies on employing high sensitivity dynamic S-Box for our DRPE system. The randomness and scalability achieved due to applied technique is an additional feature of the proposed solution. The firmness of random S-Box is investigated in terms of performance parameters such as non-linearity, strict avalanche criterion, bit independence criterion, linear and differential approximation probabilities etc. S-Boxes convey nonlinearity to cryptosystems which is a significant parameter and very essential for DRPE. The strength of proposed cryptosystem has been analysed using various parameters such as MSE, PSNR, correlation coefficient analysis, noise analysis, SVD analysis, etc. Experimental results are conferred in detail to exhibit proposed cryptosystem is highly secure.

  • Stereoscopic Video Clip Matching Algorithm Based on Incidence Matrix of
           Similar Key Frames
    • Authors: Feng-feng Duan; Si-yao Duan
      Abstract: Clip matching is the key of content-based video retrieval. In order to better realize the content-based video retrieval and improve the accuracy and efficiency, a stereoscopic video clip matching algorithm based on incidence matrix of similar key frames is proposed by integrating depth information in feature extraction. In the algorithm, the stereoscopic videos are divided into sub-sequences through shot and sub-shot segmentation, and the key frames and features are extracted. With the features of key frames, this paper proposed the visual similarity based on the incidence matrix of similar key frames, order similarity based on the maximum common sub-sequence of linearly fitting, semantic similarity based on the cross similarity of similar key frames. And then the linear expression of similar matching is built so as to realize the similarity calculation and effective matching of stereoscopic video clips. In the experiment of clip matching, the mean average recall (MAR) is increased by 3.69 and 0.29%, the mean average precision (MAP) is increased by 10.17 and 8.10%, and the mean average matching time (MAMT) is decreased by 44.35 and 38.60%, respectively, compared with the existing typical stereoscopic video retrieval algorithm SVR and the video clip matching algorithm VTD-LFF. The experimental results show that the proposed algorithm can realize stereoscopic video clip matching more accurately and efficiently.

  • A Game Theory Based Solution for Security Challenges in CRNs
    • Authors: Poonam; Chander Kumar Nagpal
      Abstract: Cognitive radio networks (CRNs) are being envisioned to drive the next generation Ad hoc wireless networks due to their ability to provide communications resilience in continuously changing environments through the use of dynamic spectrum access. Conventionally CRNs are dependent upon the information gathered by other secondary users to ensure the accuracy of spectrum sensing making them vulnerable to security attacks leading to the need of security mechanisms like cryptography and trust. However, a typical cryptography based solution is not a viable security solution for CRNs owing to their limited resources. Effectiveness of trust based approaches has always been, in question, due to credibility of secondary trust resources. Game theory with its ability to optimize in an environment of conflicting interests can be quite a suitable tool to manage an ad hoc network in the presence of autonomous selfish/malevolent/malicious and attacker nodes. The literature contains several theoretical proposals for augmenting game theory in the ad hoc networks without explicit/detailed implementation. This paper implements a game theory based solution in MATLAB-2015 to secure the CRN environment and compares the obtained results with the traditional approaches of trust and cryptography. The simulation result indicates that as the time progresses the game theory performs much better with higher throughput, lower jitter and better identification of selfish/malicious nodes. Graphical

  • A Novel Image Encryption Scheme Based on Intertwining Chaotic Maps and RC4
           Stream Cipher
    • Authors: Manju Kumari; Shailender Gupta
      Abstract: As the systems are enabling us to transmit large chunks of data, both in the form of texts and images, there is a need to explore algorithms which can provide a higher security without increasing the time complexity significantly. This paper proposes an image encryption scheme which uses intertwining chaotic maps and RC4 stream cipher to encrypt/decrypt the images. The scheme employs chaotic map for the confusion stage and for generation of key for the RC4 cipher. The RC4 cipher uses this key to generate random sequences which are used to implement an efficient diffusion process. The algorithm is implemented in MATLAB-2016b and various performance metrics are used to evaluate its efficacy. The proposed scheme provides highly scrambled encrypted images and can resist statistical, differential and brute-force search attacks. The peak signal-to-noise ratio values are quite similar to other schemes, the entropy values are close to ideal. In addition, the scheme is very much practical since having lowest time complexity then its counterparts.

  • High Performance Automatic Character Skinning Based on Projection Distance
    • Authors: Jun Li; Feng Lin; Xiuling Liu; Hongrui Wang
      Abstract: Skeleton-driven-deformation methods have been commonly used in the character deformations. The process of painting skin weights for character deformation is a long-winded task requiring manual tweaking. We present a novel method to calculate skinning weights automatically from 3D human geometric model and corresponding skeleton. The method first, groups each mesh vertex of 3D human model to a skeleton bone by the minimum distance from a mesh vertex to each bone. Secondly, calculates each vertex’s weights to the adjacent bones by the vertex’s projection point distance to the bone joints. Our method’s output can not only be applied to any kind of skeleton-driven deformation, but also to motion capture driven (mocap-driven) deformation. Experiments results show that our method not only has strong generality and robustness, but also has high performance.

    • Authors: Feifei Wan; Yong Yin; Suiyu Zhang
      Abstract: The multigrid method is widely used in fluid simulation because of its strong convergence. In addition to operating accuracy, operational efficiency is also an important factor to consider in order to enable real-time fluid simulation in computer graphics. For this problem, we compared the performance of the Algebraic Multigrid and the Geometric Multigrid in the V-Cycle and Full-Cycle schemes respectively, and analyze the convergence and speed of different methods. All the calculations are done on the parallel computing of GPU in this paper. Finally, we experiment with the 3D-grid for each scale, and give the exact experimental results.

  • Parallel Computer System for 3D Visualization Stereo on GPU
    • Authors: Anas M. Al-Oraiqat; Sergii A. Zori
      Abstract: This paper proposes the organization of a parallel computer system based on Graphic Processors Unit (GPU) for 3D stereo image synthesis. The development is based on the modified ray tracing method developed by the authors for fast search of tracing rays intersections with scene objects. The system allows significant increase in the productivity for the 3D stereo synthesis of photorealistic quality. The generalized procedure of 3D stereo image synthesis on the Graphics Processing Unit/Graphics Processing Clusters (GPU/GPC) is proposed. The efficiency of the proposed solutions by GPU implementation is compared with single-threaded and multithreaded implementations on the CPU. The achieved average acceleration in multi-thread implementation on the test GPU and CPU is about 7.5 and 1.6 times, respectively. Studying the influence of choosing the size and configuration of the computational Compute Unified Device Archi-tecture (CUDA) network on the computational speed shows the importance of their correct selection. The obtained experimental estimations can be significantly improved by new GPUs with a large number of processing cores and multiprocessors, as well as optimized configuration of the computing CUDA network.

  • Master of Puppets: An Animation-by-Demonstration Computer Puppetry
           Authoring Framework
    • Authors: Yaoyuan Cui; Christos Mousas
      Abstract: This paper presents Master of Puppets (MOP), an animation-by-demonstration framework that allows users to control the motion of virtual characters (puppets) in real time. In the first step, the user is asked to perform the necessary actions that correspond to the character’s motions. The user’s actions are recorded, and a hidden Markov model is used to learn the temporal profile of the actions. During the runtime of the framework, the user controls the motions of the virtual character based on the specified activities. The advantage of the MOP framework is that it recognizes and follows the progress of the user’s actions in real time. Based on the forward algorithm, the method predicts the evolution of the user’s actions, which corresponds to the evolution of the character’s motion. This method treats characters as puppets that can perform only one motion at a time. This means that combinations of motion segments (motion synthesis), as well as the interpolation of individual motion sequences, are not provided as functionalities. By implementing the framework and presenting several computer puppetry scenarios, its efficiency and flexibility in animating virtual characters is demonstrated.

  • Physically-Based Rendering of Particle-Based Fluids with Light Transport
    • Authors: Ali Beddiaf; Mohamed Chaouki Babahenini
      Abstract: Recent interactive rendering approaches aim to efficiently produce images. However, time constraints deeply affect their output accuracy and realism (many light phenomena are poorly or not supported at all). To remedy this issue, in this paper, we propose a physically-based fluid rendering approach. First, while state-of-the-art methods focus on isosurface rendering with only two refractions, our proposal (1) considers the fluid as a heterogeneous participating medium with refractive boundaries, and (2) supports both multiple refractions and scattering. Second, the proposed solution is fully particle-based in the sense that no particles transformation into a grid is required. This interesting feature makes it able to handle many particle types (water, bubble, foam, and sand). On top of that, a medium with different fluids (color, phase function, etc.) can also be rendered.

  • Sharpness Improvement for Medical Images Using a New Nimble Filter
    • Abstract: It is known that various medical devices introduce blur to recorded images due to many factual yet inevitable limitations. Thus, it is highly desirable to provide an efficient solution for such prevalent problem. In this article, a new sharpening filter is proposed to improve the edges and fine details of medical images. In the proposed filter, the sharpening process is achieved by deducting specific spatial information which is determined expeditiously from the original image itself with the existence of a special tuning weight that controls the amount of the produced sharpness. The aforesaid procedure helped to increase the acutance of edges and improve the overall sharpness significantly in the processed images. The proposed filter was evaluated using two advanced image quality assessment metrics and was compared with four well-known image sharpening techniques. Intensive experiments and comparisons using different 2D and 3D real-degraded medical images revealed that the proposed filter has better performance and properties than several existing techniques, and is more suitable for sharpening medical images.
