This paper introduces a new approach, TIZMs & MNN, for palmprint recognition. It uses translation invariant Zernike moments (TIZMs) as palm features, and a modular neural network (MNN) as classifier. Translation invariance is added to the general Zernike moments which have very good property of rotation invariance. A fast algorithm for computing the TIZMs is adopted to improve the computation speed. The pattern set is set up by eight-order TIZMs. Because palmprint recognition is a large-scale multi-class task, it is quite difficult for a single multilayer perceptrons to be competent. A modular neural network is presented to act the classifier, which can decompose the palmprint recognition task into a series of smaller and simpler two-class subproblems. Simulations have been done on the Polyu_PalmprintDB database. Experimental results demonstrate that higher identification rate and recognition rate are achieved by the proposed method in contrast with the straight-line segments (SLS) based method [2]. © Springer-Verlag Berlin Heidelberg 2005.
