CA 2329094

The present invention relates to a color space quantization descriptor structure for performing quantization of a color space in order to search a multimedia based on contents when multimedia feature information is color information, particularly when the multimedia feature information is the color information and the search is about a moving image or a still image, the color space quantization descriptor structure according to the present invention has a tree structure divided into a plurality steps of superior color spaces and subordinate color spaces, and the tree structure recurrently comprises a plurality of subordinate color spaces. Accordingly, the present invention can improve performace of a still image and a moving image search apparatus, perform the quantization of a n dimensional color space such as a H, S, V, RGB, HMMD color space etc., and perform the different step quantization corresponding to each feature.
