Abstract: Automated tongue image segmentation in Chinese medicine is difficult due to two special factors: (1) There are a lot of pathological details on the surface of the tongue, which have a large influence on edge extraction; (2) the shapes of tongue bodies captured from various diseases or persons are quite different, so they are impossible to be properly described by a predefined deformable template. To address these problems, We propose a technique based on the combination of a bi-elliptical deformable template and an active contour model, namely the bi-elliptical deformable contour. Applying our approach to clinical tongue images, the experimental results indicate that it is superior over both traditional deformable templates and active contour model or snakes with respect to stability and veracity.
