Point features mainly refer to the skin surface features on the palm that are similar to fingerprints, such as singular points and patterns formed locally on the mastoid lines of palm prints. It is necessary to obtain point features in high-resolution and high-quality images, so the quality of images is required.
Texture features mainly refer to lines that are shorter and thinner than lines, but irregularly distributed in the palm of your hand. The characteristics of palmprint also include geometric features, such as the width, length and geometric shape of the palm and the distribution of different areas of the palm.
The information contained in palmprint is far richer than that contained in fingerprint, and a person's identity can be completely determined by using the line features, point features, texture features and geometric features of palmprint. Therefore, in theory, palmprint has better discrimination ability and higher discrimination ability than fingerprint.
