In the study, the first hard problem is to obtain rock fracture images of a good quality, since rock surface is very rough, and is compose of complicated and multiple fractures. We used both UV (Ultraviolet) light illumination and visible optical illumination to acquire rock fracture images. The samples are resin injected, in which way; opened fractures can be seen clearly by means of UV light illumination,...
Rock fracture tracing is very important in many rock-engineering applications. This paper presents a new methodology for rock fracture detection, description and classification based on image processing technique and support vector machine (SVM). The developed algorithm uses a number of rock surface images those were taken by sophisticated CCD cameras. The studied algorithm processes all the images...

Swedish Nuclear Fuel and Waste Management Company (SKB) identified the need for a better understanding of radionuclide transport and retention processes in fractured crystalline rock. To present fracture network reasonable, we setup some models to characterize the network, based on the models, we used best fit Ferret method to auto-determine fracture zone, then, skeleton fractures to obtain endpoints,...
