The present invention discloses a video face cartoon animation generation method belonging to the image processing technology field. The video face cartoon animation generation method of the present invention comprises the following steps of firstly intercepting a frame of positive and neutral expression image from an input video, carrying out the cartoonlization processing on the neutral expression image, recording the eyebrow contour points, the eye contour points, and the maximum height difference h of the upper and lower eyelids when the eyes open; searching a frame similar with the neutral expression image as an initial conversion frame, based on the characteristic points of the last frame, determining the characteristic point processing of the next frame containing the corresponding conversion processing of the eyebrows, the eyes and the mouth, and synthesizing the converted cartoon images, obtaining the next frame image of the image frame corresponding to the synthesized cartoon images, repeating the above steps, and outputting the multiple frames of continuous cartoon images to generate the cartoon animation. The video face cartoon animation generation method of the present invention is used for the generation of the cartoon animation, is faster in generation speed and better in generation effect.
