Study on Image Processing Techniques Applying in Tongue Image Feature Analysis

Abstract

Traditional Chinese Medical. Doctors can diagnose a patient’s body by assessing the changes in the tongue proper and tongue coating. However, the diagnosis of a tongue picture was often affected by environmental and human factors. With the technical progress, many medical diagnoses can obtain the objective information from computers. The information can help doctors to diagnose more accurately and provide more suitable treatments. This research attempts to utilize image processing technologies to enhance a tongue body and separate it from a tongue image. Then we analyze the features of a tongue such as judgement of tongue color, ratio of tongue coating, and distribution of petechia and ecchymosis to assist doctors in executing tongue diagnosis.
