The video images photographed in laboratory tests were used to investigate the fissure changes in granite. Frames were extracted out and investigated using the digital image processing. The intro-frame average technique was utilized to overcome the effects of sample trembles on the image processing. The locations of the micro compositions, especially those of new-generated fissures, were examined using fractional differential. The effects of the surrounding factors on the image properties were also examined. A criterion of image characteristic parameters for generating new fissures was furthermore proposed. The method proposed herein may be used as references in analyzing the physical mechanism of deformations and failures of rock materials or rock masses in rock regions.
