Rock aperture measurement is a hot topic in many rock engineering applications. To measure rock fracture aperture using digital image processing technique accurately, it is better to divide the aperture into a number of segments first, then, measuring each of those segments. Since information of aperture is concentrated at the corners, this paper presents a corner segment algorithm for measuring rock...
In the analysis of the geometry complexity of rock joints, image processing and analysis is one of the best techniques. The measurement parameters of rock joints can be obtained by using digital image analysis technique. And the grade of geometry complexity of rock joints can be determined on considering the parameters comprehensively based on fuzzy comprehensive judgement. After image processing...
