For accurately and completely capturing the meso-structure information of coal and rock images which combine with the characteristics of inhomogeneity intensity extensively,the anthor introduces an image processing method based on Local Binary Fitting(LBF) energy model.Also,the modifications are carried out by introducing the image enhancement operators and regulating the initial set function for the defects of inefficiency in dealing with the low contrast images and the segmentation depending on the location and size of initial outline.The high-quality binary images of coal and rock meso-structure were obtained by graying,image segmentation and morphological processing for three kinds of images,and then analyzed the statistical regularity of the meso-parameters.The test results show that the image processing method based on modified LBF model can effectively deal with the uneven gray images of coal and rock,and the obtained meso-structure information can provide a true geometric model for coal and rock specimen numerical simulation and reliable technical support for meso-damage mechanics analysis.
