Journal of Information & Systems Management Y. HANYF, H. Silkan, H. Labani, S. Ouatik 3 3 2013 http://www.dline.info/jism/fulltext/v3n3/4.pdf Thanks to the development of technology of image productions and processing, the need of avoiding the traditional research based on user’s annotation is becoming more interesting; the content based image retrieval technology provides several techniques to solve this problem. In this paper we aim to propose and evaluate the combined use of D-index structure and smooth curve decomposition descriptor so as to enable accurate and fast content based image retrieval. Furthermore, this work provides an experimental analysis of D-index parameter choice and an experimental demonstration of the efficiency of D-index method through comparing its results with other known ones.
