Fuzzy color quantization and its application to scene change detection
Fu-Lai Chung, Benny Yiu-ming Fung · 2003
It is both impractical and unnecessary to use true color, i.e., 24-bit colors, for most multimedia processing tasks since the computational complexity is extremely high and adjacent colors in the color model do not contribute much to visual and computational differences. Color quantization can reduce these complexities by using less number of bits to represent the 24-bit true color space. In this paper, we investigate the fuzzy color quantization technique based on the fact that the colors located nearby should not be quantized very differently. We introduce this technique to color histogram construction and show that it achieves better performance than uniform color quantization in video scene change detection using different types of movies.
