Research ArticleOpen accessIn the abstractPan Correction through Overlap Estimation in a Multi-Camera EnvironmentS. Mohamed Mansoor Roomi, V. Manojkumar, M. SenthilarasiProblem statement: Multiple cameras are employed for surveillance of larger environment. In such a case there is a need to maintain overlap in the adjacent cameras for correct object registration. Overlap may get disturbed by natural or manual factors. This study proposed an automatic camera pan correction by determining the area of overlap from multi-view images. Approach: A closed loop … …Journal of Computer Science, Vol. 6, Issue 9 · 30 Sep 2010 · 7,275 accessesView PDFCite
Research ArticleOpen accessIn the abstractPrivacy and Social Interaction in Traditional Towns to Contemporary Urban Design in IranSamira Ramezani, Shima HamidiPrivacy as an inherent feature of Iranian culture is evident in formation of Iranian traditional towns. Put differently, attention to the inside was one of the most desirable principles in Iranian traditional architecture as well as urbanism. However, privacy did not lead to isolation in Iranian culture and social contact was also of a great importance to Iranians. Problem statement: … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 3 · 30 Sep 2010 · 8,770 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Improved Handwritten Tamil Character Recognition System using Octal GraphR. J. Kannan, R. PrabhakarProblem Statement: Handwriting recognition has attracted voluminous research in recent times. The segmentation and recognition of the characters from handwritten scripts incorporates considerable overhead. Almost all the existing handwritten character recognition techniques use neural network approach, which requires lot of preprocessing and hence accomplishing these problems using neural network is a tedious task. Approach: In this study we propose a … …Journal of Computer Science, Vol. 4, Issue 7 · 31 Jul 2008 · 7,405 accessesView PDFCite
Research ArticleOpen accessIn the abstractCASRA+: A Colloquial Arabic Speech Recognition ApplicationRamzi A. Haraty, Omar El ArissThe research proposed here was for an Arabic speech recognition application, concentrating on the Lebanese dialect. The system starts by sampling the speech, which was the process of transforming the sound from analog to digital and then extracts the features by using the Mel-Frequency Cepstral Coefficients (MFCC). The extracted features are then compared with the system's stored model; in this … …American Journal of Applied Sciences, Vol. 4, Issue 1 · 30 Apr 2007 · 7,517 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordHuman Iris Recognition Based on Hybrid TechniqueAsaad Noori Hashim, Bushraa Mahdi Al-HashimiIris recognition is a biometric technique that uses iris pattern information to detect person identification. Initially, the system find out the boundary of the pupil and iris. Then, Circular Hough transform used to find out the center of both pupil and iris in order to crop iris part from the eye image. After that, Daugman’s Rubber Sheet model utilized for … …Journal of Computer Science, Vol. 15, Issue 12 · 4 Dec 2019 · 7,802 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordHistogram Matching Schemes for Image ThresholdingSalah AmeerThis paper proposes several novel schemes for image thresholding. The idea is simply to compare the original image histogram to that of the thresholded image. Element by element comparison (sum of absolute difference between the two histograms) is found to be of better performance than a single feature (area or size) comparison. The optimum threshold is the one producing the … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 3 · 9 Sep 2019 · 7,872 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordCorrelating and Modeling of Extracted Features from PVT Images of Composites using Optical Flow Technique and Weight Elimination Algorithm Optimization [OFT-WEA]Mahmoud Zaki IskandaraniA new approach to the use and implementation of Optical Flow technique is presented. The technique extracts features from presented images as a function of reference image and produces percentage of matching between the reference and tested images. The new approach in using Optical Flow lies in replacing the motion part of the algorithm with differential time related changes in … …Journal of Computer Science, Vol. 13, Issue 9 · 29 Sep 2017 · 7,320 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordA POLYNOMIAL FUNCTION IN THE AUTOMATIC RECONSTRUCTION OF FRAGMENTED OBJECTSNada A. Rasheed, Md Jan NordinThe reconstruction of archaeological objects is a very challenging problem and solving this problem is important. Occasionally, archaeological workers suffer when trying to match object fragments together, especially when there is a presence of significant gaps in the fragments, or even in the case of similarity, where fragments are mixed with fragments of other objects. The main theme of this … …Journal of Computer Science, Vol. 10, Issue 11 · 20 Dec 2014 · 8,514 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordA Framework for MRI Image Retrieval Using Curvelet Transform and Euclidean DistanceRajakumar, MuttanContent Based Image Retrieval (CBIR) system supports users to retrieve relevant medical images based on their features. Current content based image retrieval systems are incapable of providing exact results to the users. To address this problem a consistent feature extraction method is required for content based medical image retrieval system to extract similar features from the images. In this study … …Journal of Computer Science, Vol. 9, Issue 3 · 12 Apr 2013 · 6,520 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordPrincipal Component Analysis Based Feature Extraction, Morphological Edge Detection and Localization for Fast Iris RecognitionM. Suganthy, P. RamamoorthyThis study involves the Iris Localization based on morphological or set theory which is well in shape detection. Principal Component Analysis (PCA) is used for preprocessing, in which the removal of redundant and unwanted data is done. Applications such as Median Filtering and Adaptive thresholding are used for handling the variations in lighting and noise. Features are extracted using Wavelet … …Journal of Computer Science, Vol. 8, Issue 9 · 9 Aug 2012 · 7,748 accessesView PDFCite
