Method for segmenting traditional Chinese medicine tongue images under open environment

Abstract

The invention provides a method for segmenting traditional Chinese medicine tongue images under open environment, relates to medical image processing, and aims at rapidly ad correctly segmenting tongue images for subsequent analysis so as to facilitate subsequent tongue image analysis. The method comprises the following steps of: 1) inputting an image A acquired under the open environment; 2) carrying out color correction on the acquired image A to obtain a corrected image B; 3) carrying out preliminary image segmentation on the corrected image B obtained in the step 2); 4) carrying out feature extraction on each connected domain in an image C obtained in the step 3); 5) for features of each convex hum extracted in the step 4), calculating a tongue body position by using a random forest classifier; and 6) carrying out traditional Chinese medicine tongue image segmentation on the image B by taking a tongue body area D obtained in the step 5) as basis.

Description

technical field [0001] The invention relates to medical image processing, in particular to a method for segmenting TCM tongue image images in an open environment. Background technique [0002] The traditional TCM tongue diagnosis mainly relies on the doctor's naked eye observation for analysis and judgment. The diagnosis result is often related to the doctor's knowledge level and experience accumulation. In recent years, the development of information technology has promoted the process of objectification, digitization and automation of TCM tongue analysis. . Scholars at home and abroad have carried out many beneficial explorations on this, and developed some tongue image analysis systems, which have achieved good results (Yu Xinglong, Zhu Zimin, Jin Guopan, etc. Automatic recognition system for tongue diagnosis in traditional Chinese medicine[J].

Problems solved by technology

[0010] The purpose of the present invention is to address the many deficiencies in the existing process of collecting tongue images in an open environment, such as: the influence of many uncertain factors such as the color temperature of the light source, the intensity of the light, the shooting angle, and the difference in equipment, so that the final obtained Compared with the image in a fixed environment, the collected tongue images often have large differences, which bring difficulties to subsequent analysis and other problems. Provides a quick and accurate segmentation of tongue images for subsequent analysis, so as to facilitate subsequent tongue images Analysis of a TCM tongue image segmentation method in an open environment
