基于常用的灰度变换法和直方图均衡化法等图像增强算法,提出了一种对比度增强算法.该算法首先对直方图进行平滑处理,再进行直方图均衡化,然后在整个显示范围内对图像灰度级进行等间距排列,最后对图像进行中-Gray-scale transformation based on common law and the histogram equalization method, such as image enhancement algorithm, a contrast enhancement algorithm. The algorithm first histogram smoothing processing, and then histogram equalization, and then displayed in the entire range of image gray level spacing, etc. with the final image in
