A TCM tongue image target detection method in an open environment

Abstract

The invention discloses a traditional Chinese medicine tongue manifestation object detection method in an open environment, and relates to medical image processing. The method comprises the following steps: 1, inputting an image A acquired in the open environment; 2, obtaining a correction image B by performing color correction on the acquired image A; 3, performing image segmentation on the correction image B obtained in the second step; 4, performing area feature determination on an image C obtained in the third step; and 5, performing texture feature determination on a candidate tongue body area D obtained in the fourth step. First of all, preprocessing of the color correction is performed on the image so that an influence brought by an external light source color temperature is reduced; then multiple communicating areas are obtained by segmenting the image; the candidate tongue body area is obtained by performing the feature determination on each communicating area; and finally, determination is carried out through comparing area texture features, and thus whether the candidate tongue body area is a tongue manifestation is determined. The purpose of performing object detection on the tongue manifestation in the image is finally realized, i.e., whether the tongue manifestation exists in a current picture is determined, and if so, where a tongue manifestation object is is determined.

Description

technical field [0001] The invention relates to medical image processing, in particular to a method for detecting a TCM tongue image target in an open environment. Background technique [0002] The tongue image is the image of the tongue after a person sticks out the tongue. The acquisition of the tongue image in traditional Chinese medicine mainly depends on the naked eye observation of doctors. In recent years, the development of information technology has promoted the process of objectifying, digitizing, and automating the analysis of tongue image in TCM. 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 (Jiang Yiwu. Computerized TCM Tongue Diagnosis System [J]. Chinese Journal of Integrated Traditional Chinese and Western Medicine, 2000, 20( 2): 145-147; Cai Yiheng, Liu Changjiang, Shen Lansun.

Problems solved by technology

[0008] 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 brings difficulties to subsequent analysis, and even due to the reasons of the photographer, there may be no tongue images in the collected images that can be analyzed.
