A lattice visualization method by formal concept analysis and its application to huge image database

A visualization system based on formal concept analysis is proposed, in order to represent lattice structures of large scale image database. In the proposed system, HSB color space that is suitable for human sensitivity, is employed, to draw the lattice structure of images, where the users can easily percept the overview/relationship of them. Moreover, a new image feature considering effect of saturation and brightness, is proposed. The proposed system is developed by using JAVA based program language Processing on the computer (CPU = 2.13 GHz, MM = 2 GB), and a visualization experiment is performed. Through the experiment using 1,000 images selected from Corel Image Gallery, it is confirmed the effectiveness of the proposed system, to grasp the structure in perspective and to discover new relationship.
