Pixel based tongue color analysis

Abstract

Tongue diagnosis is a distinctive and essential diagnostic measure in Traditional Chinese Medicine (TCM), and chromatic information is its most decisive characteristic which is utilized to unearth pathological changes for identifying diseases. In this paper, a computerized medical biometrics scheme is established which classify all pixels in tongue into various color classes. For train specimens, both a forward and a backward selection are employed to pick up the correct labeled pixel specimens and screen out the wrong, and then various pixels of diversified colors are classified for the tongue color analysis. The experimental outcomes are more applicable to tongue color analysis. © Springer-Verlag Berlin Heidelberg 2007.
