彩色图像增强的改进算法

Color Image Enhancement Algorithm

为提高彩色图像的整体感官效果,在研究CES(Color image Enhancement by Scaling)算法出现块效应的原因基础上,提出了一种改进算法,即各向异性扩散滤波器的ICES(Improved Color image Enhancement byScaling)。与CES相比,ICES算法在不增加计算复杂性的前提下,不仅得到了不逊于CES算法的增强效果,还能极大地抑制块效应。

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.
