This paper examined the feature extraction method based on force field transformation and developed a new approach for multi-pose ear recognition.Firstly transformed the initial gray ear image to force field and calculated the divergence of the force field to obtain the convergence feature of ear.Then employed the algorithm of null-space based linear discriminant analysis(NLDA) to complement classification and recognition.The experimental results show that the proposed method is more robust and effective than the initial feature extraction method based on force field transformation,the potential well-based method and demonstrate effectiveness for multi-pose ear recognition.
