Lip movement detection method, lip movement detection device and electronic equipment

摘要: An embodiment of the invention provides a lip movement detection method, device and electronic equipment. The method comprises steps determining position preset characteristic point area mouth image, shape changing state according to determined point; opening-and-closing which corresponds with image through pre-acquired classifier detects area, wherein is obtained after texture training image; tip result state. According equipment, identified change tip, thereby improving robustness accuracy in dynamic state, preventing an effect by environmental illumination, face distance camera.
