Rotation invariant seal imprint recognition with ring-projecting technique

摘要

In this paper, the advantage and disadvantage of several seal imprint recognition methods have been compared, and an approach for seal imprint recognition based on ring-projecting template matching is proposed. Firstly, the seal imprint is divided into some rings, and the local and global intrinsic features are extracted. Then, the recognition is made, with the border and the words of seal imprint separated, by 1-D template matching. The experimental results show that the proposed approach is of adaptability and reliability.
