Tongue picture recognition method and device based on neural network and computer equipment

Abstract

The invention relates to the field of image processing, in particular to a tongue picture recognition method and device based on a neural network and computer equipment. Carrying out feature extraction on each row of pixel points of the tongue body gray scale image to obtain tongue body influence features; based on each row of pixel points, determining a corresponding gray scale curve graph, obtaining all wave crest points and wave trough points of the gray scale curve graph, and determining the widths and heights of all wave crests; using the product of the width and the height as a morphological parameter of the corresponding gray curve graph; extracting a highlight area of each gray curve graph, and calculating a mean value parameter of all pixel points of the highlight area; according to the tongue fat and thin influence features and the morphological parameters of all the gray curve graphs, obtaining tongue fat and thin features; according to the tongue coating thickness influence characteristic and the mean value parameter, obtaining a tongue coating thickness characteristic; and inputting the tongue body fat and thin features and the tongue fur thickness features into the trained network model, and outputting a tongue picture recognition result. According to the scheme, the tongue picture can be identified.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a neural network-based tongue image recognition method, device and computer equipment. Background technique [0002] Traditional Chinese medicine has a history of thousands of years in China, and has rich clinical experience in the fields of disease treatment, disease prevention and health preservation. Among them, the diagnosis and treatment methods of traditional Chinese medicine are known for their simplicity, convenience and low cost. "The Yellow Emperor's Classic of Internal Medicine" says: "There are all kinds of shapes in the inside, and they must be in the outside." That is to say, if there is a problem in the human body, it will definitely appear on the surface of the body. Traditional Chinese medicine uses the four diagnostic methods of looking, smelling, asking, and cutting to collect the manifestations of diseases and understand the health of the human body. Among th...

Problems solved by technology

[0003] At present, the descriptive tongue diagnosis and interrogation data obtained manually by TCM professionals lack objectivity and quantification. These data are difficult for individuals to understand and do not know how to use

At the same time, unquantified and qualitative data are difficult for ordinary people to use for daily self-care
