This paper proposes an efficient palmprint searching algorithm for personal identification based on database clustering, which reduces the search space of fine matching. A complex filter is applied to double orientation field to detect the symmetry of the palm lines as the main feature at coarse-level search. A K-means clustering technique is applied to partition the symmetry feature space into clusters. A query processing is proposed to facilitate an efficient searching. The experimental results on the public database of Hong Kong Polytechnic University show the effectiveness of the proposed searching algorithm.
