  • A vision-based non-contact area and volume estimation of irregular
           structures towards applications in wound measurement
    • Authors: Shubhangi Shrivastava, Alex Noel Joseph Raj
      Pages: 489 - 501
      Abstract: Area and volume computation of irregular structures can be done using several techniques, but accuracy and the speed of computation is become an issue. But when wounds are considered for measurements, another factor comes into picture which is the risk of contamination due to direct contact with wounds and this can lead to catastrophic situations. In order to combat such issues, there is a requirement of non-contact measurement technique and thus, the paper discusses about a vision-based non-contact method for area and volume computation of irregular structures. The methodology presented here, models the irregular structured object using Delaunay triangulation and thus computes area and volume from the model formed. The new method is experimented on certain regular and irregular shaped objects and the results obtained along with their accuracy are provided.
      Keywords: irregular structures; area and volume estimation; vision-based method; non-contact method

  • Edge-based singular value decomposition for full reference colour
           image quality assessment
    • Authors: Manisha Jadhav, Yogesh H. Dandawate, Narayan Pisharoty
      Pages: 502 - 521
      Abstract: Due to intense use of digital visual aids, image quality plays a crucial role in today's life. Images are subjected to degradations during image acquisition and image processing. This affects their naturalness and usefulness in different applications. Literature shows efforts are made to develop an HVS consistent image quality metric since last few decades. New image quality metrics, extension of existing image quality algorithms and their applications are being developed by researcher's community. Singular value decomposition is one of the measures which are used to quantify the amount of distortion at different distortion levels. Based on the hypothesis that the human eye is adapted to extract edge information from any natural scene, this paper presents a novel approach of introducing edge information in SVD-based image quality metric. The results are compared with SVD-based metric available in related work in literature. Proposed metric outperforms the existing metric. Also, it is extended for evaluation of colour images.

  • A hybrid scheme of image compression employing wavelets and 2D-PCA
    • Authors: Manoj K. Mishra, Rohit Ghosh, Susanta Mukhopadhyay
      Pages: 522 - 537
      Abstract: In this paper, we have presented a method of compressing 2D grey-scale images employing wavelets and two-dimensional principal component analysis (2D-PCA). Principal component analysis (PCA) is an already established technique for image compression which primarily aims at exploiting inter pixel redundancies present in the image, while wavelet is a tool widely used in multi-resolution image processing. In the proposed method the image is subjected to a multi-resolution decomposition using wavelet. Subsequently, 2D-PCA is applied on the set of detail images at each level of resolution. The compressed form of the image is constituted by representative pairs of principal components and projection vectors from each level of resolution along with the approximate image at the coarsest resolution. The proposed method requires relatively few number of principal components (of varied dimension) to produce improved compression ratio with acceptable peak signal to noise ratio (PSNR). The method has been implemented and tested on a set of real 2D grey-scale images and the results have been assessed on both qualitative and quantitative basis by measuring parameters like compression ratio (CR), PSNR, structural similarity index measurement (SSIM) and the overall performance is found to be satisfactory.
      Keywords: 2D-PCA; feature matrix; projection vector; image compression; wavelet structural similarity index

  • Human action recognition by fuzzy hidden Markov model
    • Authors: Jalal A. Nasiri, Nasrollah Moghadam Charkari, Kourosh Mozafari
      Pages: 538 - 557
      Abstract: Hidden Markov model (HMM) has been widely applied in human action recognition. In this paper an extension of HMM called fuzzy hidden Markov model (fuzzy HMM) is used for action recognition. It tries to increase the classification performance and decrease the information loss due to feature vector quantisation. Using fuzzy concepts with HMM leads to better recognition of similar actions such as walking, jogging and running. Two feature extraction methods including skeleton and space-time approaches are used for action representation. Actions could be represented efficiently using skeleton features where scene background is plain. Space-time features are extracted directly from video, and therefore avoid possible failures of other pre-processing methods. We propose space-time-based features by considering temporal relation between them. Experimental results show the effectiveness of fuzzy HMM in human action recognition. Moreover, it is shown that fuzzy HMM leads to significant improvement in recognition of similar actions. The accuracy rates of fuzzy HMM in comparison to HMM are incremented 3.33% and 5.59% in Weizmann and KTH datasets respectively.

      Abstract: With netizens continuing to express a range of opinions and making assessments online, it has become a challenge to mine sentiments accurately from the ever-multiplying Big Data. We present a context-driven sentiment analysis scheme with the objective of refining the degree of subjectivity during sentiment analysis. The essence of our scheme is to capture in a stable manner, the mutual influence of the sentiments of neighbouring words on the sentiment of each word in a document. A parametric influence function combines the native sentiment score of each word with the context-derived sentiment score obtained from surrounding words. We apply a genetic algorithm to fine tune the parameters of the influence function so as to obtain the best possible accuracy for a given corpus. The experimental results on hotel reviews extracted from Tripadvisor.com show an average accuracy of 73.2% which is 3.6% more than the results obtained from the baseline sentiment analysis approach using native scores obtained from SentiWordNet. Though the improvement is small, it re-affirms our belief that contextual information provides valuable reinforcement of sentiment scores especially with regard to the borderline cases where words show near neutral sentiments. We also present a comparison with alternative sentiment analysis approaches that shows the strength of our proposed context-based sentiment analysis approach.

      Abstract: In the current commercial automotive market, the need for intelligent headlight control systems has increased more and more. Camera-based night-time vehicle detection has become a crucial issue in determining the performance of such control systems. The purpose of this paper is to offer an answer to the question, 'Which thresholding method is suitable in terms of detection performance for a night-time vehicle candidate selection process?' For such purposes, two local adaptive thresholding methods are introduced and tested. One is local maximum-based thresholding, and the other is local mean-based thresholding. Efficient implementation methodologies are also introduced for real-time processing. Through the simulations tested on road image sequences with different exposure times, we prove that local adaptive thresholding methods have better performance than other well-known global thresholding methods. In particular, the simulations show that the proposed mean-based thresholding method has better performance on both long- and short-exposure sequences.

  • Odia character recognition using backpropagation network with binary
           features
    • Authors: Mamata Nayak, Ajit Kumar Nayak
      Pages: 588 - 604
      Abstract: Automatic recognition of printed characters has been an area of active research since last few decades. Though considerable work has been reported for Latin, CJK, and many other popular languages, but a few works has been reported for many Indian languages. In this work, we propose a complete model with effective techniques to recognise printed offline Odia language characters. First we develop a technique to segment the image to extract characters, and then features of these segmented characters are extracted using a binary feature extraction, as well as structural feature extraction. Finally, these extracted features are used to classify character symbols using a modified backpropagation network. In each of these phases it is found that the proposed technique outperforms existing techniques and yields high accuracy rate. Further, this work has tried to include all the possible characters (approx. 2,500 characters) in training/testing unlike other works, where a small set of characters are normally considered for testing.

      Pages: 605 - 610
      Abstract: The advancements in technology drifted the individuals towards the usage of modern devices and as a result, the usage of web services has increased exponentially. As a result, the quantity of multimedia data accessed and stored across the internet is growing swiftly. Online money transactions, purchases, tenders and many other applications, such as messaging among specific groups were made possible. The usage of social networking sites have gained popularity due to its capability of sharing the videos and audios along with messaging, however, retrieving the most relevant videos is a challenging task among these networking groups. In this paper, a concept of audio tagging is used and the relevant videos are retrieved efficiently. The generalised GMM distribution is used as classifier and MFCC features are used to identify the voices associated with the videos.
