一些常用的图像处理cpp和对应的matlab接口 是非常常用的一些代码-Quick list of the source included: imhist_thresh.cpp: Generate histogram from data,# of bins based on unique values. imsmarthist_thresh.cpp: equalize data based on histogram imsmartstd_thresh.cpp: equal

灰度直方图是灰度级的函数，描述的是图像中具有该灰度级的像素的个数。它是多种空间域处理技术的基础。直方图操作能够有效用于图像增强；提供有用的图像统计资料，其在软件中易于计算，适用于商用硬件设备。直方图均衡化是通过对原图像进行某种变换，使原图像的灰度直方图修正为均匀分布的直方图的一种方法。图像灰度 直方图均衡化使得图像的灰度分布趋向均匀，图像所占有的像素灰度间距拉开，加大了图像反差，改善了视觉效果，达到增强目的。MATLAB是数字图像处理的常用工具，应用MATLAB的各种函数能够对数字图像进行各种处

This Matlab code was developed for skin pixel detection in general imagery. Non-parametric histogram-based models were trained using manually annotated skin and non-skin pixels. A total of 14,985,845 skin pixels and 304,844,751 non-skin pixels
