An algorithm is proposed for 3D face recognition in the presence of varied facial expressions. It is based on combining the match scores from matching multiple overlapping regions around the nose. Experimental results are presented using the largest database employed to date in 3D face recognition studies, over 4,000 scans of 449 subjects. Results show substantial improvement over matching the shape of a single larger frontal face region. This is the first approach to use multiple overlapping regions around the nose to handle the problem of expression variation.
提出了一种用于在存在多种面部表情的情况下进行3D人脸识别的算法。该算法基于对鼻子周围多个重叠区域进行匹配所得到的匹配分数的组合。使用了3D人脸识别研究中迄今为止所采用的最大数据库（449名受试者的4000多次扫描数据）展示了实验结果。结果表明，与匹配单个较大的正面面部区域的形状相比有显著改进。这是第一种使用鼻子周围多个重叠区域来处理表情变化问题的方法。
