Abstract: A gesture recognition system and method that inputs videos of a moving hand and outputs the recognized gesture states for the input sequence. In each image, the hand area is segmented from the background and used to estimate parameters of all five fingers. The system further classifies the hand image as one of the postures in the pre-defined database and applies a geometric classification algorithm to recognize the gesture. The system combines a skin color model with motion information to achieve real-time hand segmentation performance, and considers each dynamic gesture as a multi-dimensional volume and uses a geometric algorithm to classify each volume.

Abstract: A gesture recognition system using a skin-color based method combined with motion information to achieve real-time segmentation. A Kalman filter is used to track the centroid of the hand. The palm center, palm bottom, as well as the largest distance from the palm center to the contour from extracted hand mask are computed. The computed distance to a threshold is then compared to decide if the current posture is “open” or “closed.” In a preferred embodiment, the transition between the “open” and “closed” posture to decide if the current gesture is in “select” or “grab” state.

Abstract: The apparatus generates simulated strobe effects in the form of video or still image output in response to receipt of a video stream, and without the need of additional strobe hardware. Videos of a moving target object are categorized into one of multiple categories, from which a strobe generation process is selected. In one mode, the two categories comprise target objects with either small motion or large motions in relation to the frame size. Interoperation between image registration and cloning are utilized to produce simulated strobe motion videos or pictures. Motion segmentation is applied to the foreground object in each image frame, and a foreground mask is updated as each checkpoint is reached along the object trajectory, such as in response to time differences between checkpoints. Potential applications include special features for camcorders, digital cameras, or computer software.
