摘要:

目前,光照变化是人脸识别预处理面临的困难之一。文中对经典的去光照预处理算法包括图像增强方法、提取光照不变性、Retinex算法、对数变换等算法及其改进后的算法进行了分析和总结。最后提出了对去光照的研究方向。

关键词: 人脸识别, 去光照, 小波变换

Abstract:

At present,the illumination change is one of the difficulties in the recognition preprocessing.Classical light elimination pre-processing algorithms,including image enhancement (histogram equalization,gamma transform,and logarithmic transform),illumination invariant extraction (eigenface and quotient image),Retinex algorithm and logarithmic transformation and the improved algorithms are analyzed and summarized.Finally the future trend of light elimination research is pointed out.

Key words: face recognition;light elimination;wavelet transform
