%X Slow-motion photograph is used to study the rule of blast-induced crack developing. But the images of slow-motion are blurred because of some reasons,such as the blasting smog,which makes a bad influence on the study of crack developing. By use of computer image processing technique and wavelet transform theory,and VC++ program and MATLAB software to handle the slow-motion pictures of explosion,the crack developing velocity of marble under explosion is given based on processed images,which is helpful to the furture study of blast-induced crash mechanism of rock.
