Research ArticleOpen accessIn the abstractNON-COOPERATIVE IRIS RECOGNITION: A NOVEL APPROACH FOR SEGMENTATION AND FAKE IDENTIFICATIONM. Rajeev Kumar, M. Dilsath Fathima, K. Kiruthika, M. S. SaravananIris recognition, the ability to recognize and distinguish individuals by their pattern, is the most reliable biometric in terms of recognition and identification performance. However, performance of these systems is affected by the heterogeneous images (regarding focus, contrast, or brightness) and with several noise factors (iris obstruction and reflection) when the cooperation is not expectable from the subject. Current Iris … …Journal of Computer Science, Vol. 9, Issue 9 · 6 Aug 2013 · 6,744 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimized Local Ternary Patterns: A New Texture Model with Set of Optimal Patterns for Texture AnalysisG. Madasamy Raja, V. SadasivamTexture analysis is one of the important as well as useful tasks in image processing applications. Many texture models have been developed over the past few years and Local Binary Patterns (LBP) is one of the simple and efficient approach among them. A number of extensions to the LBP method have been also presented but the problem remains challenging in … …Journal of Computer Science, Vol. 9, Issue 1 · 22 Jan 2013 · 6,951 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Block Cipher Algorithm for Multimedia Content Protection with Random Substitution using Binary Tree TraversalP. Vidhya Saraswathi, M. VenkatesuluMany people consume multimedia content (images, music, movie) on portable devices like DVD player, MP3 player, Portable Multimedia Player and also through Internet. Problem statement: The conventional algorithms such as DES and AES cannot be used directly in multimedia data, since multimedia data are repeatedly have high redundancy, large-volumes and require real-time operations, such as displaying, cutting, copying, bit-rate conversion … …Journal of Computer Science, Vol. 8, Issue 9 · 15 Aug 2012 · 7,694 accessesView PDFCite
Research ArticleOpen accessIn the abstractStill Image Compression Using Texture and Non Texture Prediction ModelG. Mohanbaabu, P. RenugaProblem statement: Existing lossless image compression schemes attempt to do prediction in an image data using their Local Binary Pattern (LBP) and their spatial neighborhood based techniques. In the previous techniques such as Vector Quantization (VQ) and Gradient Adjusted Prediction (GAP) the texture and non-texture regions are not classified separately. Texture and Non-texture images prophecy has been a key factor … …American Journal of Applied Sciences, Vol. 9, Issue 4 · 11 Feb 2012 · 7,303 accessesView PDFCite
Research ArticleOpen accessIn the abstractExtending Binary Large Object Support to Open Grid Services Architecture-Data Access and Integration Middleware Client ToolkitKiran Kumar Patnaik, Bollam NagarjunProblem statement: OGSA-DAI middleware allows data resources to be federated and accessed via web services on the web or within grids or clouds. It provides a client API for writing programs that access the exposed databases. Migrating existing applications to the new technology and using a new API to access the data of DBMS with BLOB is difficult and discouraging. … …Journal of Computer Science, Vol. 7, Issue 6 · 14 Jun 2011 · 6,663 accessesView PDFCite
Research ArticleOpen accessIn the abstractBio-Potential Signal Extraction from Multi-Channel Paper Recorded ChartsAli S.A. Al-MejradProblem Statement: Almost all of the modern biomedical equipments that record the biopotential actions have digital output but the paper chart records are a must. The volume of these records is significant and increasing rapidly. Keeping a bio-signal chart of a patient make it easy for quick assessment but still create problems in the essence of data storage, archiving , … …American Journal of Applied Sciences, Vol. 8, Issue 6 · 13 Jun 2011 · 7,106 accessesView PDFCite
Research ArticleOpen accessIn the abstractRobust Image Watermarking Using Discrete Wavelet TransformDhandapani Samiappan, Krishnan AmmasiProblem statement: Digital Watermarking have gained popularity in recent years as a means of protecting multimedia data from illegal copying and unlawful reproduction. It is mainly used for copyright protection of multimedia data. Approach: In this study an image watermarking algorithm which is blind (do not require the presence of host image for detection) and robust is proposed. Results: The … …Journal of Computer Science, Vol. 7, Issue 1 · 16 Dec 2010 · 8,142 accessesView PDFCite
Research ArticleOpen accessIn the abstractConnected Component Labeling Using Components Neighbors-Scan Labeling ApproachAkmal Rakhmadi, Nur Zuraifah Syazrah Othman, Abdullah Bade et al.Problem statement: Many approaches have been proposed in previous such as the classic sequential connected components labeling algorithm which is relies on two subsequent raster-scans of a binary image. This method produced good performance in terms of accuracy, but because of the implementation of the image processing systems now requires faster process of the computer, the speed of this technique’s … …Journal of Computer Science, Vol. 6, Issue 10 · 30 Jul 2010 · 8,137 accessesView PDFCite
Research ArticleOpen accessIn the abstractFeature Extraction for Characterization of Breast Lesions in Ultrasound Echography and ElastographyShirley Selvan, M. Kavitha, S. Shenbagadevi, S. SureshProblem statement: Elastography is developed as a quantitative approach to imaging linear elastic properties of tissues to detect suspicious tumors. We propose an automatic feature extraction method in ultrasound elastography and echography for characterization of breast lesions. Approach: The proposed algorithm was tested on 40 pairs of biopsy proven ultrasound elastography and echography images of which 11 are cystic, 16 … …Journal of Computer Science, Vol. 6, Issue 1 · 31 Jan 2010 · 8,315 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Efficient Low Complexity Lossless Coding Algorithm for Medical ImagesS. E. Ghrare, M.A. Mohd. Ali, K. Jumari, M. IsmailProblem statement: Nowadays a large number of various medical images are generated from hospitals and medical centers with sophisticated image acquisition devices, the movement toward digital images in radiology presents the problem of how to conveniently and economically store, retrieve and transmit the volume of digital images. Thus digital image data compression is necessary in order to solve this problem. … …American Journal of Applied Sciences, Vol. 6, Issue 8 · 31 Aug 2009 · 7,091 accessesView PDFCite
