Abstract

A kind of RGB-based compression coding algorithm is proposed to gain better recovered image and efficiently remove the correlation of components in colored image. The key of algorithm is its complete DCT transformation for components of RGB. With table lookup in DCT transformation, the advantage of table lookup can have better embodiment. Result of empirical analysis on spatial coding performance of new color indicates that this method works better to remove the correlation of components of color. Besides, this algorithm has simple embodiment and better SNR. Not only does it provide excellent visual effect of image, but also it facilitates the combination with other compression and coding methods.
