Problems solved by technology

[0003] The purpose of the present invention is to overcome the above technical problems and provide a method for automatic segmentation of lip images based on inspection in traditional Chinese medicine. In the case of low contrast between lip color and skin color, the method can automatically segment the lip image from the face image. Improving the Segmentation Effect of Weak Edge Images

Embodiment Construction

[0049] The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0050] refer to figure 1 , the lip image automatic segmentation method based on traditional Chinese medicine inspection of the present invention, its concrete steps are as follows:

[0051] (1), input the original face image to be processed, carry out mean shift filter to the input face image, obtain the image I after mean shift filter, as figure 2 shown;

[0052] (2), image I is done color space conversion, obtains gray-scale image G, then normalization processing obtains normalized image G, and its specific steps are as follows:

[0053] (21), adopt grayscale conversion formula G=(0.2R-0.6G+0.3B), carry out color space conversion to image I, obtain grayscale image;

[0054] (22), using the image normalization formula G=(max(G)-G) / (max(G)-min(G)), normalize the grayscale image to obtain the image G, after normalization The pixel value of ...

Abstract

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 effect of a weak edge image can be effectively enhanced.

Description

technical field [0001] The invention relates to an automatic segmentation method of lip images based on traditional Chinese medicine inspection, and belongs to the technical field of computer digital image processing. Background technique [0002] According to the theory of observation and diagnosis of traditional Chinese medicine, the human body's five senses (eyes, ears, nose, mouth, and tongue) are related to the rise and fall of qi and blood in the five zang organs. Traditional Chinese medicine makes judgments on diseases based on its own clinical inspection experience. There is no objective unified quantitative standard for the color observation of human faces, which is not conducive to the inheritance and development of traditional Chinese medicine. To this end, computer-based image processing technology is introduced, such as "Research on Disease Diagnosis Based on Color Images of Faces published by Liu Mingjia [D]" Harbin Institute of Technology, May 2010", which int...
