Abstract
In order to examine a possible fractal organisation rock fracturation, a software of image analysis has been performed. In this paper, the method used, the different steps and possibilities of this software are explicated. The original image is digitized with a camera or a scanner, and transformed in binary image. Then for different rotation of this image around its center, the positions of the intersections with a set of parallel lines are computed and stored. For different interval values, the number of interval containing at least an intersection can then be obtained. As we have to make 10 rotation of the image from 0 to 90°. For each of them, a set of lines with another color is drawn on the image, and the intersection of these lines with the branches of fractures is stored. The distance between two lines, the minimum and the maximum of the interval of measure are optimized. Thus, it is possible to determine the fractal dimension by cantor dust method.
