Abstract: Based on the analysis of the snake model and the prior knowledge of fingerprint images,the improved snake model is used to implement fingerprint segmentation.The experimental results show that the fingerprint segmentation algorithm based on the improved snake model is more accurate than the traditional methods,which means a higher value in practice.
