Color range space of human body digital tongue image color and extraction method thereof

Abstract

The invention provides a color range space of a human body digital tongue image color characteristic and an extraction method thereof. The color range space is defined in an xyY standard color model plane defined by the CIE (Commission International Eclairage); a complete color range space and 98 percent of color range space of a tongue image are extracted; and a clustering color central point set of the color range space is extracted, so that a boundary curve of coated tongue natures is obtained. The invention provides an extraction method of the color range space of the human body digital tongue image color characteristic. The extraction method comprises the following steps of: extracting an image of a tongue body part by using edge segmentation; partitioning the image into small blocksaccording to the color consistence of the image by adopting a JSEG (J-value Segmentation) edge segmentation method; extracting edge pixels in a CIE xy space; and combining all pixels to obtain the color range space range of the image. When taken as a basic research of computer traditional Chinese medical science tongue diagnosis, the color range space of the human body tongue image can play a guidance role in extracting tongue color characteristics, separating coated tongue natures, extracting a color correction color block and the like.

Description

(1) Technical field [0001] The invention relates to medical image processing and TCM tongue diagnosis objectification technology, in particular to the color gamut space and extraction method of human digital tongue image. (2) Background technology [0002] As a traditional medical diagnostic technique, TCM tongue diagnosis technology is known as the quintessence of the Chinese nation and has made an indelible contribution to the reproduction of the Chinese nation. In order to solve the problems of subjectivity, experience, and lack of data records in the practice of tongue diagnosis in traditional Chinese medicine, medical image processing and computer analysis technology are used to realize computer-aided analysis and objectification of tongue diagnosis in traditional Chinese medicine, which is related to traditional Chinese medicine. Carrying forward and going to the world has important research significance and application prospects. The color feature of tongue image is ...

AI Technical Summary

Problems solved by technology

[0003] At present, in the process of extracting the color features of the computer-aided tongue image, due to the lack of understanding of the color gamut space of the human tongue image, there is also a lack of necessary definitions for the color range of the tongue coating and tongue quality in the theory of traditional Chinese medicine. Therefore, at present It is impossible to develop an imaging device dedicated to tongue image acquisition, nor can it give an accurate spectrum and color range definition of tongue coating and tongue quality, and it is also impossible to extract a dedicated color card for tongue image correction, which seriously affects the computer.
