【摘要】 重点研究了基于图像处理技术的光照预处理方法,先对cas-peal人脸库定位,取出人脸信息,接着分别使用直方图均衡法、直方图规定法、同态滤波法和相位图法对cas-peal人脸库进行光照预处理,再用PCA进行试验,得出各种方法的识别率,最后对这几种方法进行评价。更多还原

【Abstract】 Image processing technology based on light pre-processing methods was discussed while the method of histogram equalization,the provisions of the histogram,homomorphic filtering and phase diagram of the cas-peal illumination face database for pre-processing were applied.PCA was then employed to obtain the recognition rate of various methods.The evaluation on the methods was conducted at last.更多还原
