Oral-lip image automatic segmenting method based on Chinese medical inspection

The invention discloses an oral-lip image automatic segmenting method based on Chinese medical inspection, comprising the specific steps as follows: (1) inputting a face image and carrying out mean shift filtering on the input face image to obtain an image I; (2) carrying out color space transformation on the image I to obtain a gray level image G and carrying out normalization processing to obtain a normalized image G; (3) obtaining a contour of oral-lip segmentation; (4) establishing a level set function according to the oral-lip image contour, iteratively calculating the level set functionand moving the contour to the oral-lip edge; and (5) setting the level set function to be 0 to obtain the oral-lip image contour, processing the oral-lip image contour by utilizing a five-point average method and eliminating burrs on the edge of the oral-lip image contour to obtain a final oral-lip contour. By means of the method, the oral-lip image can be automatically segmented from the face image, and the segmentation
