Method for classifying bizygomatic colors of face on basis of support vector machine

Abstract

The invention discloses a method for classifying bizygomatic colors of a face on the basis of a support vector machine, which comprises the following steps of: (1) establishing a bizygomatic color training sample set; (2) training the bizygomatic color training sample set by utilizing the support vector machine and constructing a bizygomatic color classifier; and (3) identifying by utilizing the bizygomatic color classifier and judging whether a bizygomatic image to be identified belongs to a red bizygomatic image or a non-red bizygomatic image or not. In the method, the support vector machine is used as the classifier, R, G and B values of pixels are used as feature vectors, a computer is utilized to simulate a Chinese medical specialist to identify the bizygomatic colors, and the method has repeatability; in the method, due to the adoption of a threshold value judging method in the identification phase, a bizygomatic color judging mechanism is simpler, more visual and more impartial; the Chinese medical specialist is simulated to identify the bizygomatic colors, so that the defects of strong subjectivity and poor repeatability which are generated when the Chinese medical specialist visually observes the bizygomatic colors are overcome; and the method is obtained by summarizing and inheriting the bizygomatic color identification experience of the Chinese medical specialist.

Description

technical field [0001] The invention relates to a method for classifying two cheekbones of a human face based on a support vector machine, and belongs to the fields of pattern recognition and image processing. Background technique [0002] There are four basic methods of Chinese medicine, namely: look, smell, ask, and cut. In inspection, the color of a person's cheeks can reflect his health status. Clinically, the color of cheeks is generally divided into: red and non-red Two categories. Zygomatic redness refers to the redness of the two cheekbones on the face. The redness is mainly caused by the red blood under the skin. Traditional Chinese medicine believes that the redness of the two cheekbones is mostly a sign of yin deficiency and internal heat. Generally, zygomatic color refers to the complexion of the cheekbones. If there are obvious red blood streaks on it, it will be judged as two zygomatic reds, otherwise it is two zygomatic non-red. The traditional method of jud...

Problems solved by technology

[0003] The purpose of the present invention is to address the deficiencies in the prior art, and propose a method for color classification of two cheekbones based on a support vector machine. As the feature vector, the computer simulation of Chinese medicine experts is used to identify the color of the two cheeks, and then overcome the shortcomings of the traditional two-zygomatic color recognition of strong subjectivity and poor repeatability
