Traditional Chinese medicine human body constitution classification method based on face image and tongue image bimodal feature extraction

Abstract

The invention belongs to the field of image recognition and traditional Chinese medicine physique classification, particularly relates to a traditional Chinese medicine human body physique classification method, system and device based on face image and tongue image bimodal feature extraction, and aims to solve the problem that the physique classification result accuracy cannot reach expectation in the prior art. The method comprises the following steps: normalizing acquired two-dimensional face and tongue images, and performing 3D face recognition preprocessing, self-organizing mapping and k-nearest neighbor operation on the acquired three-dimensional face images; extracting color features and texture features of the processed two-dimensional image and geometrical features of three-dimensional data; fusing the features and reducing dimensions; and adopting a DAG-SVM multi-class classification model to obtain corresponding physique classes. The characteristics of the two-dimensional data and the characteristics of the three-dimensional data are combined, multi-angle scale information can be collected in diagnosis of some diseases, the accuracy of physique classification is improved, and therefore the accuracy of disease diagnosis is improved.

Description

technical field [0001] The invention belongs to the field of image processing and TCM constitution classification, and in particular relates to a TCM human constitution classification method based on dual-mode feature extraction of face image and tongue image. Background technique [0002] TCM physiology is a discipline that studies the characteristics of human constitution, the physiological and pathological characteristics of constitution types, analyzes the response state of diseases, the nature and development trend of diseases, and guides disease prevention, treatment and health rehabilitation under the guidance of TCM theory. Inheriting the innovations in the basic theory of Chinese medicine is also a breakthrough in the current development of the basic theory of Chinese medicine. It has made considerable progress in the inheritance of classic medical books, basic research, and clinical research, and it occupies an important position in the field of traditional Chinese...

Problems solved by technology

[0005] In order to solve the above-mentioned problems in the prior art, that is, the prior art cannot take into account the information of two-dimensional and three-dimensional data, which leads to the problem that the accuracy rate of the classification result of the human body constitution cannot meet the expectation. TCM human body constitution classification method based on modal feature extraction, the human body constitution classification method includes:
