中心/ 环绕Retinex 算法。自从Retinex 理论提出以来, Land 本人和其他

人先后提出了Retinex 不同的变种, 最新的一个版

本是中心/ 环绕Retinex 7 。该方法比较以前的版

本, 运算速度显著提高, 而且物理意义更加清楚。

这种运算与人类视网膜和大脑皮层神经元的神经生

理学函数相关, 其形式类似于自然视觉科学中常用

来模拟单个神经元感受野的高斯差分函数-center / around Retinex algorithm. Since Retinex theory, Land I and others have raised Retinex different varieties, The latest version is a center / around Retinex 7. The method compared with the old version, computational speed significantly improved, but more clear physical meaning. Such operations and human retinal neurons in the brain and nerve function related physiology, form similar to the natural visual science used to simulate the feeling of individual neurons in the wild Difference of Gaussian function
