Traditional Chinese medicine tongue diagnosis is one of the important medicine topics.The correct segmentation of the body of tongue is premise to the information on diagnosis by the feature of tongue in Traditional Chinese Medicine.The main method at present is the threshold algorithm.But the method can not deal with some tongue images with low contrast.Proposed an adaptive segementation algorithm to segment tongue image efficiently.The algorithm is based on VC + + as a development platform.First,divided the image into several parts,and then use an iterative approach to calculate each sub-block threshold.According to each local threshold to segment.The experimental results show that the algorithm can well segment the tongue image whose background and boundaries of the objectives is not obvious.
