Abstract:

To improve the overall sensory effect of color images.The CES (Color image Enhancement by Scaling) algorithm with blocking is studied and  an improved algorithm that anisotropic diffusion filter ICES (Improved Color image Enhancement by Scaling). Compared with the CES, ICES algorithm without increasing the computational complexity of the premise is propased,which is wore favorable than CES enhancement algorithms, but also greatly inhibit the block effect.

Key words: image enhancement technology, discrete cosine trunstion(DCT) technology, color image enhancement by scaling(CES) algorithm, massive
