一个matlab程序，实现图像 增加对比度、 减小对比度、线性增加亮度、反相显示-A matlab program to realize the image to increase contrast, reduce the contrast, the linear increase in brightness, reverse video

直方图及直方图均衡化，用来增加许多图像的局部对比度，尤其是当图像的有用数据的对比度相当接近的时候。通过这种方法，亮度可以更好地在直方图上分布。这样就可以用于增强局部的对比度而不影响整体的对比度，直方图均衡化通过有效地扩展常用的亮度来实现这种功能。 -Used to increase the local contrast of many images, especially when the contrast of the image of the useful data is very c

matlab源程序，增加图像亮度和色彩饱和度-Matlab source code, increase image brightness and color saturation

图像亮度增强，线性增强，提高亮度同时，尽量保持图像不失真。(Image brightness enhancement, linear enhancement, increase brightness, while trying to keep the image undistorted.)
