Retinex理论

Retinex理论始于Land和McCann于20世纪60年代作出的一系列贡献,其基本思想是人感知到某点的颜色和亮度并不仅仅取决于该点进入人眼的绝对光线，还和其周围的颜色和亮度有关。Retinex这个词是由视网膜(Retina)和大脑皮层(Cortex)两个词组合构成的.Land之所以设计这个词，是为了表明他不清楚视觉系统的特性究竟取决于此两个生理结构中的哪一个，抑或是与两者都有关系。

Land的Retinex模型是建立在以下的基础之上的：

一、真实世界是无颜色的，我们所感知的颜色是光与物质的相互作用的结果。我们见到的水是无色的，但是水膜—肥皂膜却是显现五彩缤纷，那是薄膜表面光干涉的结果；

二、每一颜色区域由给定波长的红、绿、蓝三原色构成的；

三、三原色决定了每个单位区域的颜色。

Retinex 理论的基本内容是物体的颜色是由物体对长波（红）、中波（绿）和短波（蓝）光线的反射能力决定的，而不是由反射光强度的绝对值决定的；物体的色彩不受光照非均性的影响，具有一致性，即Retinex理论是以色感一致性（颜色恒常性）为基础的。如下图所示，观察者所看到的物体的图像S是由物体表面对入射光L反射得到的，反射率R由物体本身决定，不受入射光L变化。

 

 

本来想把下面的代码改成OpenCV版本的，但是不太会把读出来的mat里面数据改成BYTE*里面，在主函数里面写的一点都注释了

后面用opencv改写了一下主要想把像素数据写到BYTE *指向的内存空间中，这样的话可以加载其他格式的图像文件了:但是出现了一些问题，可能跟之前作者代码里面的限制有关，必须是64的倍数。还写了一个功能实现把像素数据写到txt中保存下来，各位凑活看。
