The analysis of curdy and greasy property of tongue fur is of great significance in Traditional Chinese Medicine characterization and modernization.An image analysis method of curdy and greasy fur based on texture feature is proposed in this paper.First

the tongue fur region is divided into blocks with the same size; then the blocks is classified; finally the greasy index of the whole image is calculated.To classify the blocks

a modified subspace method is used to analysed the denseness of the coating texture

combined with the texture coarseness to indicate the fur grain size.Experimental results show that the correctness rate exceeds 83%

and the variances of greasy degree is also reflected.
