Research ArticleOpen accessIn the abstractAudio Environment Recognition using Zero Crossing Features and MPEG-7 DescriptorsSaleh Al-Zhrani, Mubarak AlQahtaniProblem statement: This study investigated zero crossing features and selected MPEG-7 audio descriptors for environment sound recognition applications such as audio forensics. Approach: The study implemented several experiments focusing on the problems of environment recognition from audio particularly for forensic applications. Results: It was investigated the effect of the temporal zero crossing feature as well as selected MPEG-7 audio low … …Journal of Computer Science, Vol. 6, Issue 11 · 23 Oct 2010 · 7,177 accessesView PDF Cite

Research ArticleOpen accessIn the abstractFixed Representative Colors Feature Extraction Algorithm for Moving Picture Experts Group-7 Dominant Color DescriptorAhmed Ibrahim, Ala'a Al-Zou'bi, Raed Sahawneh, Maria MakhadmehProblem statement: MPEG-7 has defined a set of color descriptors for the multimedia contents; one of these descriptors is the Dominant Color Descriptor (DCD). The DCD adopted the Generalized Lloyd Algorithm (GLA) as a feature extraction technique. However, using this algorithm in image retrieval systems may produce perceptually irrelevant images in the ranked results. Approach: In this study, we proposed … …Journal of Computer Science, Vol. 5, Issue 11 · 30 Nov 2009 · 7,542 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordLogo Recognition System Using Angular Radial Transform DescriptorsOmar Mohammed Wahdan, Khairuddin Omar, Mohammad Faidzul NasrudinProblem statement: The shape-based logo recognition systems have been developed to automate the logo registration process. The logo recognition operation faces many challenges such as having to recognize logos that might be scaled, rotated, translated and added with noises. Different types of logo’s shapes further add to the complex nature of this problem. Approach: We developed a logo recognition system … …Journal of Computer Science, Vol. 7, Issue 9 · 26 Jul 2011 · 7,197 accessesView PDF Cite
