Histeq
Enhance contrast using histogram equalization
该函数通过直方图均衡化来增加对比度
Syntax
J = histeq(I,hgram)
Description
Histeq enhances the contrast of images by transforming the values in an intensity image, or the values in the colormap of an indexed image, so that the histogram of the output image approximately matches a specified histogram.
Histeq函数通过改变一副亮度图像灰度值或者一副索引图像的灰度值来增加图像的对比度,以达到输出图像的直方图近似于规定的直方图。
J = histeq(I,hgram) transforms the intensity image I so th
