Automatic analysis method of tongue color and coating color in traditional Chinese medicine based on image retrieval

Abstract

The invention discloses an automatic analysis method of a tongue color and a coating color in traditional Chinese medicine based on image retrieval, and belongs to the field of interdiscipline of information science and traditional Chinese medicine. In view of the characteristics that a result of tongue diagnosis in traditional Chinese medicine varies with different individuals, has strong subjectivity and lacks of normalization and standardization, the automatic analysis method of the tongue color and the coating color in the traditional Chinese medicine based on the image retrieval is designed. The automatic analysis method is characterized by comprising the following steps of inputting a tongue image to be analyzed by a user, firstly, segmenting a tongue body region through a tongue body segmentation technology, carrying out regional division on a tongue surface, distinguishing a tongue nature region and a coated tongue region, distinguishing a visual feature of the image in each region so as to form a feature vector, secondly, computing similarity of the feature vector and the feature of a tongue picture of a marked tongue image in a feature library, returning a most similar image as a retrieved result, and lastly, judging the retrieved result by utilizing a method of statistical decision, and respectively giving classification suggestions to the tongue color and the coating color in the tongue picture. According to the automatic analysis method, a classification result is more accurate and has a certain practical value.

Description

technical field [0001] The invention belongs to the interdisciplinary field of information science and traditional Chinese medicine. Taking TCM tongue image as the research object, combined with the diagnosis and treatment experience of TCM experts, using content-based image retrieval technology, it focuses on analyzing the visual information such as the color, texture, and shape of the tongue image, extracts the corresponding content features, and forms a description of the content of the tongue image. feature vectors to retrieve. Then, according to the similarity between the tongue image to be analyzed and the retrieval results, the statistical decision-making method is used to make statistical judgments on the retrieval results to determine which category the tongue color and fur color belong to, and realize the automatic analysis of TCM tongue color and fur color. The invention will provide a brand-new means and method for automatic analysis of tongue color and fur color ...
