Research on Harris Corner Detection Method in Palmprint Recognition System

Palmprint location is the premise of feature space extraction and feature recognition, the speed and accuracy of palmprint location directly affect the speed and accuracy of palmprint recognition system, and the extraction of contour feature points is the key of palmprint location. The contour of palmprint is extracted by gray morphological gradient; then, based on the analysis of palmprint appearance characteristics, Harris corner is used to extract the key feature points of the image, and the reference coordinate system is established according to the key points to realize the location and segmentation of palmprint.
