Tongue fur texture identification method based on Gabor wavelet transformation

Abstract

The invention relates to a method for identifying greasiness of the tongue fur and belongs to the field of tongue fur data processing. A tongue fur texture identification method based on Gabor wavelet transformation is characterized by comprising following steps of carrying out dilation operation on an acquired whole tongue image, and carrying out edge expansion through extraction and assignment of edge points so as to obtain a tongue body expansion image subjected to the boundary filling; establishing a Gabor wavelet family, and carrying out Gabor wavelet transformation on the whole tongue body subjected to the image expansion; multiplying the tongue image subjected to the Gabor wavelet transformation with the binary image of the tongue body of the original whole tongue image so as to obtain a Gabor wavelet transformation tongue image whose edge effects have been removed; extracting a mean value and a standard difference from the Gabor wavelet transformation tongue image whose edge effects have been removed and using the mean value and the standard difference as features so as to carry out classification identification on the tongue fur textures. According to the invention, in the obtained whole tongue image, the texture features of the tongue fur are quite precise, so the identification accuracy rate is improved and beneficial reference is provided for objective diagnosis in the traditional Chinese medicine.

Description

technical field [0001] The invention relates to a method for identifying greasy tongue coating, in particular to a method for identifying tongue coating texture based on Gabor wavelet transform. Background technique [0002] Tongue examination is a diagnostic method to understand the body's physiological functions and pathological changes by observing the changes in tongue quality and coating. It is an important content of inspection and one of the characteristics of traditional Chinese medicine diagnosis. Tongue diagnosis in traditional Chinese medicine is mainly based on visual observation and empirical analysis by doctors. The diagnosis results are not only limited by the doctor's knowledge level, thinking ability and diagnostic skills, but also affected by external objective conditions such as light and temperature. There is no constant objective evaluation standard. , which affects its promotion and inheritance, and is not conducive to scientific research, teaching and ...
