Hand shape and hand gesture recognition

Abstract

We present two problems in the article, first concerns persons identification based on the shape of the hand and the second recognizing gestures and signs executed by hands. Hand-based authentication schemes in the literature are mostly based on invariant geometrical features, typically including length and width of the fingers, aspect ratio of the palm or fingers, thickness of the hand, etc.. These features are not as discriminating as other biometric characteristics, however they can easily be used for verification purpose. Gesture recognition is the process by which gestures formed by a user interact with the computer or is the element of the special signs language to convey meaning. In this paper are propose a method for the recognition of hand gestures using geometrical and Radon transform (RT) features.
