Automatic seal identification using fluency function approximation and relaxation matching method

An automatic seal identification method using a relative relation among segments of the seal impression is proposed. Features of a seal impression image are extracted by fluency function approximation, and matching is performed by relaxation matching. 2 (seals) /spl times/ 2 (sets) images are used to verify the performance of the present method. The recognition rate is 88.8%, and the processing speed for observing and matching is about 30 s on middle scale computers.<>
