Method for recognizing fissured tongue based on support vector machine

Abstract

The invention discloses a method for recognizing a fissured tongue based on a support vector machine. The method for recognizing the fissured tongue based on the support vector machine comprises the following steps that (1) a fissured tongue feature training sample set is established; (2) a fissured tongue classifier based on the support vector machine is established; (3) the fissured tongue classifier based on the support vector machine is used for conducting recognition, and whether each sample to be detected in a fissure feature sample set of the tongue to be detected belongs to a fissured tongue picture is recognized. According to the method for recognizing the fissured tongue based on the support vector machine, reorganization can be further conducted based on a detected suspected tongue fissure area. The method is the continuation of an existing computer fissured tongue detection method. By the adoption of the method for recognizing the fissured tongue based on the support vector machine, through training of a disposable sample set, recognition work can be completed, setting of any other parameters and artificial factor intervention are not needed in the recognition process, and full-automatic recognition of the fissured tongue is achieved.

Description

technical field [0001] The invention relates to a cracked tongue recognition method based on a support vector machine, which belongs to the technical field of image processing. Background technique [0002] There are four basic methods in Chinese medicine, namely: looking, smelling, asking, and feeling. In inspection, a person's tongue can reflect his health status. Clinically, the characteristics of the tongue include cracks, tooth marks, tongue coating, ecchymosis, petechiae, etc., and they all play different indicating roles in the diagnosis. Among them, there are cracks in the tongue, commonly known as cracked tongue, which is characterized by Deep grooves are formed on the back of the tongue, some grooves are arranged like leaf veins, and some are like brain lines, so the cracked tongue is also called leaf vein tongue and brain pattern tongue. If ordinary patients have signs of cracked tongue, most of them are accompanied by symptoms such as excessive heat and injury t...

Problems solved by technology

[0004] The object of the present invention is to propose a cracked tongue recognition method based on a support vector machine for the deficiencies in the prior art. The parameters r and statistics such as the span of the suspected tongue crack area and the area-span ratio are used as feature vectors to automatically identify the cracked tongue by computer simulation of experts in traditional Chinese medicine, thereby overcoming the problems of strong subjectivity and poor repeatability of traditional cracked tongue identification. shortcoming
