In order to dispel the correlation between color components of color images more efficiently and get the better color images compression results

in this paper

a new approach to decorrrelate color components of color images is presented based on the color information matrix. A quantization and encoding scheme is provided in the new color space according to the characters of the new color components respectively. Similar to the KLT color space

the new color space is also data dependent which can take full advantage of the inherent correlation between color components of original images. It differs

however

from the KLT color space in the optimal standards. The KLT color space is optimal when the original color components of images have been centralized

while the new color space is optimal when the original color components of images have not been centralized. Many experiments are carried out to analyze the encoding performance in the new color space. The results show that the new approach can get rid of the correlation between color components of color images efficiently and is easily implemented. It also boasts of better signal to noise ratio and higher compression rates. The reconstructed image is visual comfort and the coder is easily combined with other compression and encoding methods.
