Optimizing similarity based visualization in content based image retrieval

In any CBIR system, visualization is important, either to show the final result to the user or to form the basis for interaction. Advanced systems use 2D similarity based visualization which shows not only the information of one image itself but also the relations between images. A problem in interactive 2D visualization is the overlap between the images displayed. This obviously reduces the search capability. Simply spreading the images on the screen space will not preserve the relations between them. In this paper, we propose a visualization scheme which reduces the overlap as well as preserves the general distribution of the images displayed. Results show that an effective balance between display of structures and limited overlap can be achieved
