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 I

Embodiment 1

[0020] Example 1: Combining figure 1 , the present invention is a color gamut space of a digital tongue image of a human body. The color gamut space of a digital tongue image of a human body is defined in the xyY standard color model plane defined by the International Commission on Illumination. The area of ​​the rectangular boundary range (S1), the boundary curve (L1) representing the complete color gamut space of the digital tongue image, the largest rectangular boundary range area (S2) representing the 98% color gamut space of the digital tongue image, and the 98% of the digital tongue image The boundary curve (L2) of % color gamut space, the cluster center point set (P1) of digital tongue image color gamut space, and the boundary curve (L3) of tongue coating and quality.

[0021] The color gamut space of the digital tongue image of the human body is inside the region (S1) representing the maximum rectangular boundary range of the complete color gamut space of the digital t...

Embodiment 2

[0028] Example 2: Combining figure 1 , the human body digital tongue image color gamut space of the present invention is constructed based on the analysis and extraction of the color characteristics of a large number of human tongue images. Through standardized tongue image collection equipment, a total of more than 3,000 effective tongue images have been collected, of which about 1,600 are healthy or sub-healthy images collected by physical examination centers and outpatient clinics, and the remaining more than 1,400 samples are collected by different wards. Tongue images of disease characteristics, a total of more than 100 tongue images of diseases have been collected. Considering the standardization of collection (that is, the color quality of each collected sample is guaranteed through color restoration), the diversity and comprehensiveness of collected samples, and the large number of collections; therefore, it can be considered that the tongue image analysis data used ha...

Embodiment 3

[0056] Embodiment 3: The technical problem to be solved by the present invention is that, based on a large amount of tongue image data collected through standardization (>3000 samples, which respectively include sample images of different human physiological conditions such as health and disease), it is proposed to describe human body digital Tongue image color gamut space, corresponding mathematical description, and the distribution characteristics of typical features of tongue image in the color gamut space.

[0057] The solution proposed by the present invention for the above-mentioned technical problems is: to propose a method for extracting the color gamut space of a digital tongue image of a human body, and construct a description human body in the CIE xyY standard color model plane (CIE chromaticity diagram) defined by the International Commission on Illumination. The color gamut space of the digital tongue image color, including the complete and 98% color gamut space an...

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 ...
