The edge detection technology of CT image for study the growth of rock crack

Coal seam is a dynamic and nonlinear system, building a analysis model tally with the actual situation is necessary to numerical simulation. the growth of rock crack is the most informasion for coal mine safety, image processing technology of rock crack is introduced into the analysis of growth of crack, it use the algorithm of wavelet transform to detect the edge of CT image, the crack would be quantitative measured. Simulation verifies the effectiveness of the model.
