同态滤波在人脸识别中的应用研究

Homomorphic Filtering Application Stusy on Face Recognition

论文首先对人脸识别进行了介绍,通过对人脸识别系统的分析指出预处理在人脸识别中的重要性。然后对已有的人脸识别预处理法作了详细的介绍,并对各种方法进行比较。最后针对光照对人脸图像的影响还提出了同态滤波的方法,在预处理阶段消除光照对人脸图像的影响,实验结果表明,此种方法可以提高识别率。

Firstly,face recognition,the face recognition system that the importance of pretreatment in face recognition.And then gave a detailed description of existing face recognition preprocessing method,and comparison of methods.Finally,the impact of illumination on the face images homomorphic filtering method in the preprocessing stage to eliminate the impact of illumination on human face images,experimental results show that,this method can improve the recognition rate.
