A Novel Approach for Automatic Tongue Deviation Analysis with Auto-Correction
The article analyzed the old tongue deviation analysis method and introduced a new tongue deviation analysis method with auto-correction aiming at the shortcomings in the old method. This method overcomes the shortcoming that the old method utilized area symmetry to extract central axis and we utilizes the method of shape symmetry analysis to improve the accuracy. In comparison experiment, this method is more accurate than the old one and its efficiency is higher than the old one.
