    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.

    摘要： The invention relates to a gesture recognition system for remote controlling a TV, which comprises: (a) video capturing device for capturing a video sequence of a user which is composed of video frames, and conveying the same into a hand tracker; (b) hand tracker module for receiving said video sequence, inspecting each of said video frames for possible inclusion of a user hand within it, and when a hand is determined to be found in a frame, calculating the hand centroid, and outputting the centroid coordinates into a trajectory buffer; (c) trajectory buffer for receiving from said hand tracker each of said hand centroid coordinates, and maintaining in storage at least several tens of recent hand centroids, that altogether define a trajectory; (d) trajectory segmentation module for continuously inspecting said buffer for possible inclusion of relevant trajectories that are suspected to relate to a hand gesture pattern, and whenever a relevant trajectory is detected, extracting a trajectory segment of the same, and conveying it into a gesture classifier; and (e) gesture classifier for extracting from each received trajectory segment global feature parameters of the same, comparing said extracted global feature parameters with gesture global predefinitions, concluding whether the segment relates to a specific gesture command, and in the affirmative case, transferring the command to the TV.
