  • Two approaches-based L2-SVMs reduced to MEB problems for dialect
           identification
    • Pages: 1 - 18
      Abstract: The recent progress in speech and vision has issued from the increased use of machine learning. Not only does the machine learning provides many useful tools, it also help us to understand existing algorithms and their connections in a new light. As a powerful tool in machine learning, support vector machine (SVM) leads to an expensive computational cost in the training phase due to the large number of original training samples, while minimal enclosing ball (MEB) presents limitations dealing with a large dataset. The training computation increases as data size becomes large, hence in this paper, we propose two improved approaches that handle this problem in huge dataset used in different domains. These approaches, based on L2-SVMs reduced to MEB problems result in a reduced data optimally matched to the input demands of different background of systems such as Universal Background Model architectures in language recognition and identification systems. We experiment on speech information based on acoustic shifted delta coefficient feature vectors applied in GMM-based dialect identification system where all data outer the ball defined by MEB are eliminated and the training time is reduced. Further numerical experiments on some real-world datasets show proof of the usefulness of our approaches in the field of data mining.

  • Towards a distributed and parallel schema for active appearance model
           implementation
    • Pages: 19 - 40
      Abstract: In this paper, we propose a distributed and parallel schema to implement the standard version of active appearance model segmentation approach proposed by Cootes. In the scheme distributed, we project to integrate the parallelism to implement the model operations. The parallel schema proposed is based on the data parallelism. The majority of operations of the model lend themselves well to the parallelism. We quote the alignment procedure and the calculation of intensity profiles. These two operations belong to the stage of modelling shape. The proposed schema is intended to exploit the benefits built in the area of parallel and distributed image processing. We theoretically demonstrate the feasibility of the parallel approach for the first model operations, in order to generalise this approach to other operations. This implementation is still being and is aiming to exploit the benefits of the recent software tools such as Java-RMI, and parallel programming.

  • Frame differencing-based segmentation for low bit rate video codec
           using H.264
    • Authors: S. Sowmyayani, P. Arockia Jansi Rani
      Pages: 41 - 53
      Abstract: In video sequence coding, a combination of temporal and spatial coding technique is used in order to remove the predictable or redundant image content and encode only the unpredictable information. The objective of video compression technique is to increase the coding efficiency and to increase the data rate savings. A segmentation-based compression method is proposed to achieve this goal. In this paper, static portions are identified using frame differencing method and segmented during the encoding process. This encoded information is passed to the synthesiser. In synthesis, information which is passed during segmentation process is added to reconstruct the video. This method is integrated with the conventional video codec H.264/AVC video codec. Experimental results substantially proved the data rate is reduced by as much as 25%.

  • RVM-based human action classification through Gabor and Haar feature
           extraction
    • Authors: S. Maheswari, P. Arockia Jansi Rani
      Pages: 54 - 64
      Abstract: Human action recognition plays a vital role in surveillance applications. Human action recognition is motivated by some of the applications such as video retrieval, video surveillance systems, human robot interaction, to interact with deaf and dumb people etc. The aim is to analyse the role of Adaboost in the process of recognising the human action by extracting the motion features using optical flow. Adaboost is a supervised learning method used to select the subset of frames with most discriminatory motion features. Saliency point computation is performed to assign a measure of interest to each visual unit. Mean shift algorithm is then used for tracking the objects. Gabor feature is the global feature that includes more detailed information of frequency and orientation. Haar feature is used to show the variation in the pixel. Relevance vector machine classification gives a probabilistic output through Bayesian inference. The proposed system reduces the computation time and provides a higher recognition rate in comparison with existing gentle boost-based recognition system.

  • Using ROI with ISOM compression to medical image
    • Authors: Imen Chaabouni, Wiem Fourati, Med Salim Bouhlel
      Pages: 65 - 76
      Abstract: The availability of images in different applications are augmented owing to the technological advancement. Hence, image compression has proved to be a valuable technique as one solution. This paper gives the review of compression techniques. Based on this, we recommended some general guidelines to choose the best compression algorithm for a medical image. In this method, the ROI is encoded separately using ISOM with high priority and high resolution and the back ground (BG) region which has a lower priority is separately encoded with a low resolution version of the ISOM. Finally, the two regions are merged together to get the reconstructed image. Our results show that the proposed method gives very good image quality for diagnosis without any degradable loss. The performance of the compression technique is evaluated using the parameters (MSE, and PSNR) and achieved better result compared to other existing methods. As a result, we strongly believe that using our method we can overcome the limitations in storage and transmission of medical images that are produced day by day.

  • Genetic algorithms-based dominant feature selection for face detection
           application
    • Authors: Ameni Yangui Jammoussi, Sameh Fakhfakh Ghribi, Dorra Sellami Masmoudi
      Pages: 77 - 93
      Abstract: A key challenge in computer vision applications is detecting objects in an image which is a non-trivial problem. One of the better performing proposed algorithms falls within the Viola and Jones framework. They make use of Adaboost for training a cascade of classifiers. The challenges of Adaboost-based face detector include the selection of the most relevant features which are considered as weak classifiers. However, selection of features based on lowering classification error leads to high computation complexity. To overcome this limitation, a novel genetic Adaboost is proposed in our work. In the same context of optimisation, a selection method based on Pareto concept of the most relevant features referred to as dominant features is proposed. This optimisation allows to reduce the initial feature space by 28%. Moreover, we notice that dominant features with genetic Adaboost further improve the performance of genetic Adaboost, reducing the total number of features by 20%.

  • Automatic number plate recognition system by character position method
    • Authors: Birmohan Singh, Manpreet Kaur, Dalwinder Singh, Gurwinder Singh
      Pages: 94 - 112
      Abstract: Automatic number plate recognition (ANPR) is an important image processing technology used to recognise number plates of vehicles. Plate localisation and character recognition are two stages of ANPR. In this paper, a methodology has been proposed to develop robust ANPR system. A new algorithm has been proposed for number plate localisation which is based on character positioning method. Character recognition is done with support vector machine in which feature vector is calculated by recursive sub-divisions of character image. The problem of similar shape characters has been solved by syntactic analysis of number plate format for a particular geographical region. The system has been tested on 419 sample images from various countries with various variations in viewing angles, illuminations and distances. Experimental results show that the proposed system detects number plates and recognise characters successfully. The overall success rate of plate localisation is 97.21% and recognition of number is 95.06%.

  • Automatic continuous speech recogniser for Dravidian languages using the
           auto associative neural network
    • Authors: J. Sangeetha, S. Jothilakshmi
      Pages: 113 - 126
      Abstract: In recent times with the extensive improvement of computers, numerous methods of data interchange between man and computer are revealed. It aims to provide an efficient way for human to communicate with computers exclusively for people with disabilities who face diversity of obstacles while using computers. This paper predominantly focuses on developing an efficient speech recognition system for Dravidian languages such as Tamil, Malayalam, Telugu and Kannada. The proposed CSR system comprises of four steps namely pre-processing, feature extraction, automatic continuous speech segmentation and classification. The most powerful and widely used short term energy and zero crossing rate is used for continuous speech segmentation and Mel frequency cepstral coefficients (MFCC), linear predictive cepstral coefficients (LPCC) and shifted delta cepstrum (SDC) feature extractions are used for recognition system. Experiments are carried out with real time Dravidian languages speech signal. It is observed from the results that the proposed system gives significant results in AANN classifier with MFCC feature when compared with LPCC and SDC features.

  • Multiobjective genetic algorithm-based adaptive wavelet design
    • Authors: Sameh Fakhfakh Ghribi, Ameni Yangui Jammoussi, Dorra Sellami Masmoudi
      Pages: 127 - 145
      Abstract: Wavelet performances differ from one application to another and from one database to another. In this case, one can try to find out for each application the appropriate wavelet transform which results in better performances and consumes minimal resources once implemented on an FPGA platform. Accordingly, we use a generic lifting wavelet transform with p<SUB align="right">0 and q parameters. Thus, we train the optimisation process with a multi-objective genetic algorithm for optimising wavelet transform with respect to specific applications. Optimised criteria are related to wavelet regularity and the undertaken application performances. We consider pattern recognition and image compression applications processed respectively on ORL database and a fingerprint database. Compared with DB 4 and DB 9/7, the improvement of the criterion related to the application reaches 17% for pattern recognition application and preserves, approximately, the same values for still image compression in addition to the minimisation of the hardware cost.

  • Image denoising based on adaptive spatial segmentation and multi-scale
           correlation in directionlet domain
    • Authors: R. Sethunadh, Tessamma Thomas
      Pages: 146 - 167
      Abstract: Directionlet transform (DT) has become popular over the last few years as an efficient image representation tool due to its fine frequency tiling and directional vanishing moments along any two directions. A novel denoising algorithm based on DT is proposed here for images corrupted with Gaussian noise. The image is first spatially segmented based on the content directionality. Then an undecimated version of DT is applied to effectively capture the directional features and edge information of these segments. The DT coefficients so obtained are then modelled using a bivariate heavy tailed Gaussian distribution and the noise free coefficients are computed using MAP estimator. By employing bivariate probability distribution, the heavy-tail behaviour of natural images is accurately modelled and the interscale properties of DT coefficients are properly exploited. In addition, the local variance parameter of the model is estimated based on classification of DT coefficients within a particular scale using context modelling. Due to this the intrascale dependency of the directionlet coefficients is also well exploited in the enhancement process. The proposed algorithm is competitive with the existing algorithms with better results in terms of output peak signal-to-noise ratio while having comparable computational complexity. It exhibits good capability to preserve edges, contours and textures especially in images with abundant high frequency contents.

  • Shape descriptors-based generalised scheme for handwritten character
           recognition
    • Authors: Tusar Kanti Mishra, Banshidhar Majhi, Ratnakar Dash
      Pages: 168 - 179
      Abstract: In this paper, we propose a novel scheme for recognition of handwritten numerals for a regional language Odia of the Indian continent. Additional attempts have also been made to implement this scheme for recognition of handwritten numerals of two other languages namely, Bangla and English. Thus, the proposed scheme has been generalised to three different languages. Three variants of time series description of global shapes of numerals have been wrapped up in a vector. This vector is treated as the primary features for the suggested scheme. Satisfactory overall accuracy rate of 96.25% is achieved for Odia numerals. Promising results are also obtained for recognising English and Bangla numerals.

      Abstract: The great challenge, in blind audio watermarking, is to recover the transparent embedded information with minimum errors even in presence of disturbances. Some signal disturbances like MPEG compression and filtering can be modelled as fading-like distortions. Besides the inaudibility constraint, the problem will be viewed as the conception of a particular communication system, where our purpose is to reduce host interference noise (HIN) and inter-symbol interference (ISI) on one hand and to deal with fading perturbations on the other hand. In this paper, we propose adapting multi-carrier (MC) modulation, widely used in wireless communications, to the watermarking context. Our main motivation is to exploit advantages of MC modulations in order to outperform spread spectrum (SS) audio watermarking schemes. The new MC-watermarking system allows us to improve detection reliability and to increase robustness of the embedded watermark. Moreover, the inaudibility constraint will be ensured by adapting the MC signal parameters to the masking characteristics of the human auditory system (HAS).
