| 摘 要： | 针对单一人耳识别对姿态变化鲁棒性较差的问题,鉴于人脸在图像性质和生理位置上与人耳具有相似性和互补性,使用了多模态特征融合的方法提高姿态变化下的识别率.与传统的独立成分分析首先获得独立的基向量(ICAl)不同,提出了利用ICA直接获得独立的鉴剐特征的方法(ICA2).在USTB图像库上分别将两种ICA特征进行单模态和多模态的融合.实验表明,两种特征的融合提高了单一模态的识别率,并且多模态识别优于单一的人耳或人脸识别.

| Abstract: | The performance of single ear recognition is very poor when there is a pose variation.Because the properties of ear and face images are similar and the positions of the two features are complimentary,we improve the recognition rate using multi-modal feature fusion method.Aiming at difference from conventional independent Component Analysis(ICA1),we proposed a deformation of it to obtain statistical independent feature vectors directly(ICA2).The results of ICA feature fusion on the USTB database show that th... |
