Paper Abstract

Most color output devices use the frame buffer architecture. Although the high speed computer with large memory storage can manipulate the true color image, some applications on computer games and the Internet still needs to use K colors. Her, we propose a fast method of color image quantization based on color-distortion theory. It has the best tradeoff between the color number of quantization and the distortion. To utilize the properties of the human visual system, the distortion is also measured in the luminance-chrominance color space. Simulation shows that the proposed algorithm can produce good quantized color image and is much faster than the K-d tree algorithm.
