Embodiment Construction

[0083] exist figure 1 In the block diagram of the TCM tongue image analysis system, digital cameras and USB interfaces are commercially available, mainly to collect tongue images, convert the optical signals of the tongue body and color code into image electrical signals and input them to the computer, which is convenient for computer processing and transmission and other operations; the computer processing is mainly to read / write the tongue image through the USB interface software, and the processed tongue image is output to the buffer for easy display. The monitor is an image output device, through which the human eye can view the original tongue image and analysis results. Tongue body analysis is to carry out quantitative analysis and qualitative description of tongue color, fur color and fur thickness on the tongue image read by computer, and output the analysis results.

[0084] The original tongue image can be an image collected in real time by a digital camera, or it ...

Abstract

The tongue colour, fur colour and tongue for thickness analysis method of traditional Chinese medicine based on the multiclass vector machine is characterized by that a digital code camera can be used for making image acquisition, said image can be transferred into processor of computer by means of USB interface, in the processor the tongue body zone can be separated out from the tongue image. Said method also includes the following steps: on the basis of making hierarchical cluster analysis to form cluster tree and makijng regulation it dadopts the support vector machine based on cluster tree to make tongus body zone pixel identification, and devides the class quantity of the pixel identification into 15 kinds of classes, tongue surface can be divided into 5 zones, then the tongue colour description, fur colour description, thickness quantitative analysis and description can be made, and its result can be displayed.

Description

technical field [0001] The present invention relates to the field of computer medical image processing, and designs a TCM tongue image analysis system based on multi-class support vector machines, which performs quantitative analysis and qualitative description of tongue color, fur color, tongue coating thickness, and assists TCM diagnosis . Background technique [0002] Tongue examination is an important part of inspection in the four examinations of traditional Chinese medicine. Tongue diagnosis is to rely on the doctor to observe the tongue, so as to make a judgment. This method is highly subjective and ambiguous, and the diagnosis results are closely related to the doctor's experience. At present, people strive to conduct objective and quantitative analysis of tongue image features, overcome the subjectivity of traditional visual observation, and improve the reliability of tongue diagnosis, which has great advantages. [0003] Using computer image processing technolog...
