Embodiment Construction

[0014] A tongue image extraction method that combines color and space information. The system used includes a digital camera 1, a data line 2, and a PC 3. The digital camera is used to take pictures of the patient's protruding tongue, and then the original tongue image is passed through The data line is transmitted to the PC, and then the original tongue image file is called and processed by the TCM tongue image extraction software to extract the tongue body area, that is, the tongue image.

[0015] The hardware requirements in the system are as follows: the digital camera adopts a digital camera with more than 5 million pixels to ensure a certain definition; the PC adopts a PentiumIV 1.7G or higher processor, a memory of 256M or more, and at least 2G or more of the remaining hard disk space. The software requirements in the system are as follows: the operating system is Windows XP, and the software development platform is Visual C++ 6.0. In the case of the above minimum confi...

Abstract

A tongue picture drawing method mixed with color and space information includes 1 utilizing a digital camera to right face the face, the teeth, the lips and the tongue body of a patient for photograph; 2 searching any starting pixel close to color harmony and brightness of a tongue picture in the pictures, enabling the starting pixel to serve as a target area and ordering the color harmony of adjacent pixels in the target area according to similarity; 3 selecting pixel having smallest color harmony characteristic difference with the target area according to above ordering results and adding the pixel into a data structure of the target area; and 4 repeating the above process till all the adjacent pixels satisfying the above constraint condition into the target area to achieve the effect that the final target area is an extracted tongue picture area. The method is high in accuracy, good in reliability, strong in practicability, low in cost and capable of quickly extracting furred tongue pictures and non-furred tongue pictures.

Description

technical field [0001] The invention relates to a tongue image extraction method which can automatically extract tongue images from face, lips and teeth areas and integrates color and space information. Background technique [0002] Tongue diagnosis is the main research content of the four diagnostic methods of traditional Chinese medicine: looking, smelling, asking, and looking to the heart. It is a characteristic diagnostic method of Chinese medicine. Traditional tongue diagnosis mainly relies on doctors of traditional Chinese medicine to observe various characteristics of the tongue to make a judgment on the patient's condition. Traditional tongue diagnosis not only relies on the knowledge and experience of doctors of traditional Chinese medicine, but also the diagnosis results of tongue diagnosis will be interfered by environmental factors, so it has strong subjectivity. Some researchers use digital cameras to take pictures of the tongue, and use computer image processi...
