In this paper, we introduce some improvements of geometric hashing pattern recognition method for the purpose of real-time object detection applications. Firstly, the pattern is decomposed into some sub-patterns to reduce the data number in hash table bins. Second the sub-patterns are record in a plurality of hash tables. Finally we improve the recognition performance by combining with image pyramid and edge direction information. Both complexity analysis and experiment evaluations have demonstrated the efficiency of this technique.
