HSV阴影消除及YUV阴影消除对比代码及使用说明

1、精选优质文档-倾情为你奉上基于matlab 的HSV阴影消除代码，毕设所用，用完贡献先给代码 后有说明function varargout = untitled(varargin)% UNTITLED M-file for untitled.fig% UNTITLED, by itself, creates a new UNTITLED or raises the existing% singleton*.% H = UNTITLED returns the handle to a new UNTITLED or the handle to% the existing singleton*.%

2、 UNTITLED(CALLBACK,hObject,eventData,handles,.) calls the local% function named CALLBACK in UNTITLED.M with the given input arguments.% UNTITLED(Property,Value,.) creates a new UNTITLED or raises the% existing singleton*.
