The analysis of explosive image characteristics based on the fractal dimension of gray level image

In this paper, the explosive images are converted to gray level image and the interference factor in explosive is removed on the basis of fractal theories and digital graphic processing techniques. The method of box counting dimension is adopted by MATLAB to calculate the fractal dimension of the explosive images. The changes of fractal dimension at various moments are studied, and the change law is thus inferred, which lays the foundation for building explosive models.
