A human-machine interaction method based gesture recognition

The present invention discloses a method of computer interaction based gesture recognition, a gesture image is first captured through the camera video stream, the video stream into an image frame; then extracts from the image the shape and features of the gesture based on a particular algorithm, and a position information, establishing classification criteria for recognition of the gesture; or coordinates the operation command then mapped according to a certain system command gesture shape and position, and then drive a particular system operation simulation system mouse events on demand, human-computer interaction. The present invention provides human-computer interaction based gesture recognition can replace the traditional mouse, it can be widely used in food and beverage shopping, entertainment, big-screen presentations or conferences and other scenes, enhance the interaction between the human.
