Abstract: For the special characters of human’s tongue, when directly segmenting the tongue’s image, over-segmentation and over-merging always exist. Based on the characters of the tongue’s image, this paper combines one of the Graph theory image segmentation methods and multi-resolution image segmentation together to segment the image on two different resolutions. Based on the two results’ situation, “AND” or “OR” operation is used to deal with them and the tongue body is exacted from the image. In practice, this method can effectively avoid the above problems.
