Research of Tongue Image Analysis Instrument Based on Image Analysis

Objective To develop a kind of tongue image analysis instrument which is used to deal with the deviation problem on the process of tongue image analysis currently. Methods The system included two parts:hardware and software. The hardware was made up of special tongue image acquisition device and computer. With the application of digital image analysis technology, the instrument implements functions such as tongue image collection, image preprocess, image segmentation and feature analysis. Results After a certain amount of sample study process, the accuracy of tongue shape recognition was about 90%. Conclusion This instrument can achieve the aim of tongue information objectification and are widely used for clinical medicine and teaching.
