Research on the Analysis Method for Red Tip of Tongue and Tongue Petechia

The analysis of red tip of tongue and tongue petechia is significant to the studies on externalization of application of tongue inspection of Traditional Chinese Medicine. On the analysis of the red tip of tongue, the Optimal Threshold Iterated Algorithm is utilized in order to make the tongue coating separate from the tongue texture. It is diagnosed that whether the tip of tongue is red or not after analysing the tongue coating and the tip of tongue in HSI color space. About the tongue petechia, the digital image processing techniques are applied to the preliminary processing of the image. In the following step, the algorithm of Region Growing is adopted. The analysis method for red of tongue and tongue petechia proposed in this paper can be used to extract the feature information of tongue image and assist the diagnosis of TCM syndrome type. Experimental results verified the effectiveness of the presented method.
