The order morphology transform method improves the evaluation guide of transform  and chose the percentile value and structure B value by the Maximum Tsallis entropy of the area where the coefficient q is 0.8  enhances the gray image. Experiments show that the method enhances the image contrast and suppressing noise and extracting edge. The histogram and gray value show that the image contrast is improved. 2009 IEEE.
