Self-Organization in Image Retrieval

This chapter provides a comprehensive study on modern approaches in the area of image indexing and retrieval on the use of Self-Organization as a core enabling technology. It begins with the development of Content-based image retrieval (CBIR) systems, which includes the implementation of a radial basis function (RBF) based relevance feedback (RF) method. The chapter presents automatic and semiautomatic methods in multimedia retrieval, using the pseudo-RF for minimizing user interaction in a retrieval process. It introduces a framework for a novel extension of the self-organizing tree map (SOTM) for hierarchical clustering, the Directed SOTM (DSOTM). It demonstrates an optimized architecture for an automatic retrieval system based on collaboration between the DSOTM and the Genetic Algorithm (GA). A study on the feasibility of the proposed feature weight detection scheme in conjunction with the DSOTM, SOTM, and self-organizing feature map (SOFM) classifier techniques is presented.
