    摘要:

    对如何选取和表示人脸的Gabor特征、如何融合多通道Gabor的识别结果进行了研究.提出了一种多通道Gabor人脸识别方法:依据各通道特征可分离性判据确定特征提取区域、计算通道权值,采用模糊加权规则融合多通道的识别结果.该方法降低了特征冗余度;考虑了各通道识别能力的差异性;更好地解决了分类“边界”问题.在AR, CAS-PEAL-R1, YaleB和ORL人脸库上的实验结果表明,本文方法较传统多通道Gabor表征方法具有更高的识别率,平均识别时间较传统整体表征有较大的优势.

    Abstract:

    After studying how to select and represent Gabor features of human face, how to combine the recognition results of different Gabor channels, a face recognition method based on multichannel Gaborface representation (MGFR) was proposed. Firstly, feature areas and calculated weight in each channel were selected according to class separability of Gabor features. Then, fuzzy weighted rule was used to combine all the recognition results of different channels. This method can reduce the effect of redundancy information. Meanwhile, it takes advantage of the difference between channels and solves the boundary classification problem. Experiments on AR, CAS-PEAL-R1 and YaleB show that the proposed method has a higher recognition rate than the traditional MGFR. Simultaneously, it was compared with ensemble Gaborface representation (EGFR), which shows it has a great advantage in average recognition time.
