Tongue body color identification method and device based on image processing

Abstract

The invention discloses a tongue body color identification method and device based on image processing. The method comprises the following steps: firstly, extracting a complete tongue body; processingthe hue component and the brightness component of the tongue body image in the HSI color space through histogram equalization, then carrying out image fusion and tongue body extraction, the method issimple and easy to understand, high universality is achieved for segmentation and extraction of images with differences between target areas and background areas of tongue bodies, and the tongue bodyextraction effect is good; moss separation is carried out in a Lab color space by utilizing a K-means clustering algorithm; and finally, the data is converted into a Maxwell color triangular chromaticity coordinate system, and tongue quality coated tongue color identification is carried out by utilizing the improved r and g thresholds, so that the method is simple, the universality is relativelyhigh, and the accuracy is relatively high. According to the invention, traditional Chinese medicine tongue diagnosis color features are embodied and digitized, so that the diagnosis result is more accurate, and the situation that traditional Chinese medicine tongue diagnosis depends on subjective experience of doctors is avoided.
