Research ArticleOpen accessIn the abstractComplexity in Human Perception of Brightness: A Historical Review on the Evolution of the Philosophy of Visual PerceptionKuntal Ghosh, Kamales BhaumikProblem statement: The “eye-brain” complex, which contributes maximally to visual perception, is no doubt a very interesting object for complexity study. In this review we shall try to present some of its aspects in perceiving brightness. It is a well-known fact that the perceived brightness of any surface depends on the brightness of the surfaces that surround it, a phenomenon … …OnLine Journal of Biological Sciences, Vol. 10, Issue 1 · 30 Jun 2010 · 8,680 accessesView PDFCite
Research ArticleOpen accessIn the abstractMeasure of Departure from Average Cumulative Symmetry for Square Contingency Tables with Ordered CategoriesKouta Miyazawa, Sadao Tomizawa, Kouji TahataProblem statement: For square contingency tables with ordered categories, we are interested in considering a structure of weak symmetry when Bowker's symmetry model does not hold and in measuring the degree of departure from weak symmetry. Approach: The present study considered the average cumulative symmetry model that has a weaker restriction than the structure of symmetry. It also gave a … …Current Research in Biostatistics, Vol. 1, Issue 1 · 30 Jun 2010 · 7,621 accessesView PDFCite
Research ArticleOpen accessIn the abstractDevelopment and Validation of a Measure of Relational Leadership: Implications for Leadership Theory and PoliciesJames CarifioProblem statement: This study reports the development and validation of the Relational Leadership Questionnaire (RLQ). The consensus attributes of relational leadership are that the relational leader is caring, empowering, ethical, inclusive and has vision. These characteristics also reflect the newest theory and view of leadership in the psychological literature as well. Approach: For each of these 5 attributes, 10 Likert … …Current Research in Psychology, Vol. 1, Issue 1 · 20 Jun 2010 · 40,434 accessesView PDFCite
Research ArticleOpen accessIn the abstractIntelligent Sensor for Image Control Point of Eigenfaces for Face RecognitionMohamed Lamine Toure, Zou BeijiProblem statement: The sensor for image control point in Face Recognition (FR) is one of the most active research areas in computer vision and pattern recognition. Its practical application includes forensic identification, access control and human computer interface. The task of a FR system is to compare an input face image against a database containing a set of face samples … …Journal of Computer Science, Vol. 6, Issue 5 · 31 May 2010 · 6,974 accessesView PDFCite
Research ArticleOpen accessIn the abstractDecomposition of Marginal Homogeneity into Logit and Mean Ridits Equality for Square Contingency TablesKiyotaka Iki, Kouji Tahata, Sadao TomizawaProblem statement: For square contingency tables with ordered categories, if the Marginal Homogeneity (MH) model holds, then the probability that X selected at random from the row marginal distribution is less than Y selected independently at random from the column marginal distribution equals the probability that X is greater than Y. However, the converse does not hold. We are interested … …Journal of Mathematics and Statistics, Vol. 6, Issue 1 · 31 Mar 2010 · 7,297 accessesView PDFCite
Research ArticleOpen accessIn the abstractSolving Square Jigsaw Puzzles Using Dynamic Programming and the Hungarian ProcedureNaif AlajlanProblem statement: To design, implement, and test an algorithm for solving the square jigsaw puzzle problem, which has many applications in image processing, pattern recognition, and computer vision such as restoration of archeological artifacts and image descrambling. Approach: The algorithm used the gray level profiles of border pixels for local matching of the puzzle pieces, which was performed using dynamic … …American Journal of Applied Sciences, Vol. 6, Issue 11 · 30 Nov 2009 · 7,690 accessesView PDFCite
Research ArticleOpen accessIn the abstractResponse Fusion in Multi-Agent EnvironmentFereshteh-Azadi Parand, Nasrollah Moghaddam Charkari, Sara AfrasyabianMulti agent environment are often complex, while each member of agent community has vision about only a part of the environment. In such environment, information fusion of agent community is vital to attain a better accuracy or quality of information. Agents have different ability and can access to information sources with different degree of credibility. As a result, information which … …American Journal of Applied Sciences, Vol. 6, Issue 1 · 31 Jan 2009 · 7,165 accessesView PDFCite
Research ArticleOpen accessIn the abstractSelf-Generation ART-1 Neural Network with Gradient-Descent Method Aid for Latin Alphabet RecognitionMbaïtiga ZacharieProblem statement: In this study a self-generation ART-1 neural network that is an efficient algorithm that emulates the self-organizing pattern recognition developed to avoid the stability-plasticity dilemma in competitive networks learning, is presented for Latin alphabet recognition to use in a vision system for road sings recognition. Approach: The first step of our approach deals with the training process where … …Journal of Computer Science, Vol. 4, Issue 8 · 31 Aug 2008 · 6,566 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimized Set of RST Moment InvariantsKhalid M. HosnyMoment invariants are widely used in image processing, pattern recognition and computer vision. Several methods and algorithms have been proposed for fast and efficient calculation of moment's invariants where numerical approximation errors are involved in most of these methods. In this paper, an optimized set of moment invariants with respect to rotation, scaling and translation is presented. An accurate method … …American Journal of Applied Sciences, Vol. 5, Issue 6 · 30 Jun 2008 · 7,069 accessesView PDFCite
Research ArticleOpen accessIn the abstractOperating System Support for Wireless Sensor NetworksAnt A. Fröhlich, Lucas F. WannerIn a wireless sensor network, several sensor nodes obtain local data and communicate among themselves in order to create a global vision of an object of study. The idea of a self-managed network of low-power, autonomous devices, that collects data from an environment and propagates information through a wireless link brought about several new challenges and requirements in application run-time … …Journal of Computer Science, Vol. 4, Issue 4 · 30 Apr 2008 · 7,382 accessesView PDFCite
