摘要
重点阐述了人脸图像光照预处理的3种算法:灰度值增强、灰度直方图均衡化、小波变换。运用Matlab软件并选用ORL人脸库进行了相应实验,验证了3种算法的可行性。
It focuses on three algorithms of face image illumination preprocessing:gray value enhancement,gray histogram equalization,and wavelet transform.Using Matlab software and selecting ORL face database,corresponding experiments were conducted to verify the feasibility of the three algorithms.
