人脸图像光照预处理方法[Matlab]
光照预处理是人脸识中种有效的处理光照变化的方法。
近年来涌现出一系列人脸光照预处理方法，但针对这些方法的系统对比与分析的工作相对较少，本文在系统比较现有方法的基础上提出了人脸光照预处理方法的新见解和结论，以及如何设计更好的预处理方法。
我们对12种具有代表性的光照预处理方法进行比较研究（HE，LT，GIC，DGD，LOG，SSR，GHP，SQI，LDCT，LTV，LN和TT），着重于两个新的角度：（1）全局方法的局部化和（2）大尺度和小尺度特征带的融合。
在公开的人脸数据库（Yalebext，CMU-PIE，CAS-PEAL和FRGCv2.0）上的实验表明，对全局的光照处理方法（HE，GIC，LTV和TT）进行局部化进一步提高了功能。
对（SSR，GHP，SQI，LDCT，LTV和TT）等方法进行大尺度和小尺度的融合有助于光照不变的人脸识别。
