摘 要: 利用Gabor滤波器进行特征提取时,不同的Gabor滤波器参数所提取的特征具有不同的特点,首先从理论上分析了Gabor滤波器不同的时域(频域)窗口尺寸、不同的Gabor滤波器方向对所提取特征的影响;然后分析不同Gabor滤波器模板尺寸对所提取特征的影响;最后利用CAS-PEAL-R1人脸库进行仿真实验. When extracting features of images by Gabor filters, different Gabor filters' parameter can extract different characteristic features of images. Therefore, the paper firstly analyzes that Gabor filters of different sizes and different orientation have different characteristics, and then analyzes that Gabor filters of different size templates have different characteristics. Finally, some experiments are executed on CAS-PEAL-R1 face data.
