Automatic detection system and method for tongue image in traditional Chinese medicine technology

Abstract

The invention discloses an automatic detection system and method for a tongue image in the traditional Chinese medicine technology, wherein the system and method are applied to a computer. The method comprises: an image acquisition device is controlled to shoot a clear tongue image; the tongue image is segmented to obtain a tongue image; a color feature and a texture feature of a coating on the tongue are extracted from a tongue region and feature values of tongue coating thickness, tongue coating dryness, and tongue coating greasyness are analyzed based on the color feature and texture feature of the coating; the length and the width of the tongue print are detected and are quantified into a feature value for describing a tongue print situation; the tongue surface size is detected and is quantified into a feature value for describing the thin degree of the tongue body; and the features of the tongue coating thickness, the tongue coating dryness, the tongue coating greasyness, the tongue print situation, and the tongue thin degree are combined into a multi-dimensional tongue image feature vector. The image acquisition device can be controlled automatically to shoot the clear tongue image and various attributes of the tongue body can be analyzed and identified automatically, so that the reference basis can be provided for the tongue diagnosis in the traditional Chinese medicine technology.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a system and method for automatic detection of tongue images in traditional Chinese medicine. Background technique [0002] Traditional Chinese medicine includes the four diagnosis of "look, smell, ask, and feel", and tongue diagnosis is the key content of inspection, which is a must-see item in TCM clinical practice.
