Xie Jian-jun · Caai Transactions on Intelligent Systems · 2008
Multi-pose ear recognition is a challenging problem in ear recognition technology,and it has not received sufficient attention.In this paper,on the basis of the manifold learning algorithm,we propose a multi-pose ear recognition method based on LLE(locally linear embedding)that overcomes the disadvantages of 2-D ear recognition methods in dealing with pose variations.Experimental results show that this method can obtain a satisfactorily high recognition rate,improving the robustness of ear recognition,and enhancing the practicability of ear recognition technology.
