Design of control system based on hand gesture recognition

Vision-based dynamic gesture recognition is an important means of human-computer interaction. This paper designs a dynamic gesture recognition control system based on USB single camera. After obtaining the image through the camera, the original image is binarized, eroded, smoothed and filled with holes, then the circumscribed rectangles and the centroid points of the gesture image are tracked, then the movement direction of the gesture is determined according to the motion track. Finally, through the gesture control movement of the mouse pointer to move and simulate the left-click operation. The test results show that the system recognition rate is high, therefore the research has some practical values.
