基于opencv1.0的gamma变换程序，首先接受用户输入，然后计算查找表，最后查表得到变换后的图像。-The gamma transform procedures based on opencv1.0, first to accept user input, and then calculates the lookup table, the last look-up table to obtain the converted image.

计算图像的直方图，通过查找表修改图像外观，直方图均衡化，反投影直方图以检测特定的图像内容，实用均值漂移算法查找物体，实用比较直方图检索相似图片-Files: histogram.h histograms.cpp correspond to Recipes: Computing the Image Histogram Applying Look-up Tables to Modify Image Appearance Files: colorhistogra
