Research ArticleOpen accessIn the abstractIndoor Navigation and Localization for Visually impaired people Using Weighted Topological MapMd Jan Nordin, Abbas M. AliProblem Statement: Image base methods are a new approach for solving problems of navigations for visually impaired people. Approach: The study introduced a new approach of an electronic cane for blind people using the environment represented as a weighted topological graph instead, each node contains images taken at some poses in the work space, instead of building a metric (3D) … …Journal of Computer Science, Vol. 5, Issue 11 · 30 Nov 2009 · 7,420 accessesView PDFCite
Research ArticleOpen accessIn the abstractHuman 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 accessIn the abstractEXPLOITING SOCIAL TAGS TO OVERCOME COLD START RECOMMENDATION PROBLEMA. S. Ghabayen, Shahrul Azman NoahThe practice and method of collaboratively creating and managing tags to annotate and categorize content has resulted in the creation of folksonomy. Folksonomies provide new opportunities and challenges in the field of recommender systems. Despite the considerable amount of researches done in the context of recommender systems, the specific problem of integrating tags into standard recommender system algorithms is less … …Journal of Computer Science, Vol. 10, Issue 7 · 18 Feb 2014 · 7,084 accessesView PDFCite
Research ArticleOpen accessIn the abstractMorphological Features of Rodoretto Valley Deep-Seated Gravitational Slope DeformationsMaria Gabriella Forno, Andrea Lingua, Stefano Lo Russo, Glenda TaddiaA new, detailed survey of the Rodoretto Valley (Western Alps, Italy) has been conducted resulting in the production of a new morphological and quaternary geological map of the area. The authors used the innovative Solid (True) Ortho-Photo (STOP) technology integrated with navigation sensors (Global Navigation Satellite System-GNSS/Inertial Measurement Unit-IMU). This state-of-the-art procedure has demonstrated several operational advantages during both the … …American Journal of Environmental Sciences, Vol. 8, Issue 6 · 9 Feb 2013 · 7,031 accessesView PDFCite
Research ArticleOpen accessIn the abstractHuman Face Detection and Recognition using Web-CamPetcharat Pattanasethanon, Charuay SavithiProblem statement: The illuminance insensitivity that reflects the angle of human facial aspects occurs once the distance between the object and the camera is too different such as animated images. This has been a problem for facial recognition system for decades. Approach: For this reason, our study represents a novel technique for facial recognition through the implementation of Successes Mean … …Journal of Computer Science, Vol. 8, Issue 9 · 17 Aug 2012 · 8,271 accessesView PDFCite
Research ArticleOpen accessIn the abstractRule Based Shallow Parser for Arabic LanguageMona Ali Mohammed, Nazlia OmarProblem statement: One of language processing approaches that compute a basic analysis of sentence structure rather than attempting full syntactic analysis is shallow syntactic parsing. It is an analysis of a sentence which identifies the constituents (noun groups, verb groups, prepositional groups), but does not specify their internal structure, nor their role in the main sentence. The only technique used … …Journal of Computer Science, Vol. 7, Issue 10 · 4 Aug 2011 · 7,183 accessesView PDFCite
Research ArticleOpen accessIn the abstractUse of Quantitative Polymerase Chain Reaction for Determining Copy Numbers of Transgenes in Lesquerella fendleriGrace Qianhong Chen, Jiann-Tsyh LinProblem statement: In transgenic plants, the number of transgene copies could greatly influence the level of expression and genetic stability of the target gene, thus it is important to develop an efficient method for accurate estimation of transgene copies. The quantitative Polymerase Chain Reaction (qPCR) technique is becoming more efficient nowadays to determine copy numbers of transgenes in transgenic plants, … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 3 · 30 Sep 2010 · 8,191 accessesView PDFCite
Research ArticleOpen accessIn the abstractUsability Requirements of Formal Verification Tools: A SurveyRozilawati Razali, Paul GarrattProblem statement: Formal notations employ mathematical symbols and interpretation to illustrate system elements. The formality imposed by the notations allows the accuracy and consistency of a system model to be confirmed by verification tools. Formal notations on the other hand are difficult to understand and use by most users. As supporting instruments, verification tools are expected to be as usable … …Journal of Computer Science, Vol. 6, Issue 10 · 10 Aug 2010 · 7,185 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnalyzing the Peer to Peer Traffic Aggregation Using an Optimized MethodM. Sadish Sendil, N. NagarajanProblem statement: In the recent years, peer to peer networks have rapidly developed in the distributed and decentralized world of internet. Current research indicated that P2P applications were responsible for a substantial part of Internet traffic. Number of users embracing new P2P technology is also increasing fast. It is therefore important to understand the impact of the new P2P services … …Journal of Computer Science, Vol. 5, Issue 10 · 31 Oct 2009 · 6,607 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign of a Neural Networks Classifier for Face DetectionF. Smach, M. Atri, J. Mitéran, M. AbidFace detection and recognition has many applications in a variety of fields such as security system, videoconferencing and identification. Face classification is currently implemented in software. A hardware implementation allows real-time processing, but has higher cost and time to-market. The objective of this work was to implement a classifier based on neural networks MLP (Multi-layer Perception) for face detection. The … …Journal of Computer Science, Vol. 2, Issue 3 · 31 Mar 2006 · 6,885 accessesView PDFCite
