Real-time user identification by hand motion signatures

摘要

A system for real time user identification based on a user-decided 3D hand motion gesture representing his/her signature, which comprises a 3D camera for acquiring images of the 3D gestures when performed in front of the camera; a memory for storing the images; a computer for analyzing images representing trajectories of the gesture and for extracting typical features related to the user during a training stage; a screen for displaying a typical trajectory containing the features to the user; a database for storing the typical features after the training stage; and a processing unit for comparing the typical features extracted during the training stage to features extracted online.
