Abstract

A random walk tongue image extraction method based on multi-rule fusion comprises the following steps that initial segmentation is performed on an original image by utilizing a toboggan algorithm with a reduced rule, so an initial range set is acquired; a composite weighting function is utilized for establishing a weighted graph, and simplification is performed; final cluster segmentation is performed by utilizing a random walk tongue image extraction method based on multi-rule fusion, so a tongue body area image is generated; finally, a target area is trimmed through mathematical morphology operators, so pinholes in the tongue image area are eliminated, and a target tongue image is obtained. The random walk tongue image extraction method is high in intelligent degree, the whole extraction process is completed in a full-automatic mode, the efficiency of the random walk algorithm is greatly improved, the time required by tongue image extraction is shortened, and a tongue image can be successfully and accurately extracted from the image containing a tongue coating.

Description

technical field

[0001] The invention relates to a multi-rule fused random walk tongue image extraction method capable of automatically extracting tongue images from background areas such as faces, lips and teeth. Background technique

[0002] Tongue diagnosis is the main content of inspection in the four diagnosis methods of traditional Chinese medicine, and it is a characteristic diagnosis method in traditional Chinese medicine. Traditional tongue diagnosis mainly relies on doctors of traditional Chinese medicine to subjectively identify the characteristics of the patient's tongue image, such as the quality of the tongue, the color, texture, shape, and thickness of the tongue coating, so as to make reasonable inferences about the patient's condition. Traditional tongue diagnosis mainly relies on the diagnostic experience of doctors of traditional Chinese medicine, and the results of tongue diagnosis are easily affected by human subjective and objective environments.
