Palmprint Recognition Using Band-Limited Minimum Average Correlation Energy Filter

In this paper, we propose Band-Limited minimum average correlation energy filter and unconstrained minimum average correlation energy filter for palmprint recognition, in which the high frequency components are removed and only the inherent frequency band is adopted for filter design. The results of experiments conducted on Hong Kong Polytechnic University Palmprint Database show that the proposed filters can significantly improve accurate recognition rates and reduce equal error rates. Meanwhile, they also have faster matching speed and need less feature storage.
