Palm Recognition

Palmprint recognition is one type of biometric identification that primarily uses the length and width of fingers as features. However, currently, palmprint images must be captured with the user's hand placed on a fixed point, making it impossible to apply to all hand sizes, such as those of children. Maintaining a high recognition rate without a fixed palm is an area worth studying. Palmprint recognition is a relatively new research field, so many challenges exist, such as noise interference caused by image capture, unstable patterns, and how to find stable features.
