| 摘 要： | 本文提出了一种新的非线性变换法进行图像增强处理的方法．将整个灰度范围划分为几个子区问，在这些子区间内红，绿，蓝三色交替由最小值线性变换为最大值，但在整个灰度范围内灰度映射是非线性的．采用该方法处理后的数字图像人眼分辨率明显优于原始数字图像，可获得更多的视觉细节信息．

| Abstract: | A new non-linearity transform method is proposed for image enhancement. The whole tonal range is divided into several subintervals, but the map of shade of gray is nonlinear in the whole tonal range. In the sub- zones, red, green and blue, three colors linear are transformed alternately from the minimum to the maximum. The eye resolution of new digital image is clearly enhanced and much visible detail information is obtained in the new digital image. |
