Tongue picture drawing method mixed with color and space information

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.
