摘要: 选用在生理位置上具有一定关联性的人耳和人脸作为研究对象,针对剧烈的姿态变化会造成融合信息大量缺损的问题,提出了一种基于核典型相关分析的多模态识别方法,利用标准化和中心化两种方法对原始数据集进行预处理,并用最近邻方法进行分类识别.实验结果表明,核典型相关分析方法可以有效地克服剧烈的姿态变化对人耳和人脸识别的影响,且与单生物特征相比,识别率显著提高.Abstract: Using the ear and face possessing of special physiological correlation under the same pose condition as the research object, a muhimodal recognition method based on kernel canonical correlation analysis (KCCA) was proposed to solve the problem of information loss resulted from sharp pose change. In the method, the normalization and centering methods were used to preproeess ear and face datasets and the nearest neighbor method was used to classify. Experimental results show that KCCA can availably overcome the effect of sharp pose change. Compared with the single biometric, the recognition rate improves remarkably.
