Palmprint segmentation is an important task for palmprint recognition. By the segmentation operation, an expected area of each palmprint can be extracted for the future feature extraction and matching. In the paper, an improved square-based segmentation method for palmprint alignment and extraction is presented. The approach successfully extracts three key points in a local area. The outside boundary...
A novel method for palmprint recognition based on wavelet transform is presented in this paper. Because palmprint's principal lines, wrinkles and ridges have characteristics of various resolutions, a method for multi-scale wavelet transform analysis is utilized in palmprint recognition. There are three steps in the scheme, which are image preprocessing, feature extraction and recognition. Original...
