Embodiment Construction

[0040] The following is attached figure 1 The embodiments of the present invention are further described in detail.

[0041] The present embodiment implements on the premise of the technical solution of the present invention:

[0042] Such as figure 1 Shown, the method for automatic lip color recognition based on support vector machine of the present invention, its concrete steps are as follows:

[0043] (1) Create a lip color training sample set:

[0044] (11) Establish a lip image library: use the lip segmentation algorithm to segment the lips of 290 face photos, obtain 290 lip images, save them in the lip image library, identify the lip colors of all lip images and record the recognition results, and implement In the example, the lip color is divided into five categories: dark red, light red, red, purple and pale white;

[0045] (12), using the histogram interval subdivision method to extract the histogram feature vector of the lip image to form a lip color training sam...

Abstract

The invention discloses a method for automatically recognizing a lip color based on a support vector machine. The method comprises the following steps of: (1) establishing a lip color training sample set: firstly, establishing a lip image library; and secondly, extracting the histogram characteristic vector of a lip image by using a histogram interval subdivision method to form a lip color training sample set; (2) training the lip color training sample set by using the support vector machine to establish a lip color classifier; and (3) recognizing the lip color of a new lip image by using the lip color classifier. By adopting the histogram characteristic vector obtained with the method, fine difference information on different lip colors can be captured; the lip color is recognized by simulating traditional Chinese medical science, so that the defects of strong subjectivity and poor repeatability of the conventional method are overcome; and a training lip image is judged in advance by a well-known traditional Chinese medicine expert and the lip image is recognized by learning, so that the method is the conclusion and the inheritance of lip color recognition experience in traditional Chinese medicine.

Description

technical field [0001] The invention relates to a method for automatic lip color recognition based on a support vector machine, which belongs to the field of pattern recognition and image processing. Background technique [0002] Looking at the lips to diagnose diseases is one of the important contents of traditional Chinese medicine inspection. Traditional Chinese medicine believes that: the spleen is opened in the mouth, its splendor is in the lips, and the meridian of the Stomach Meridian of Foot Yangming surrounds the lips, so looking at the lips can diagnose the lesions of the spleen and stomach. The color change of the lips is related to the ups and downs of qi and blood in the five viscera, which can be used to diagnose visceral lesions. Normal people's lips are ruddy, which is a sign of sufficient stomach qi and well-balanced qi and blood. Once there is a problem with the body, the lips will change. Clinically, lip color is generally divided into five categories: ...
