Keywords:image processing; vertical fracture; image segmentation, automatic identification
Abstract: According to the changes of grayscale or colour in imaging logging data, the principle of fracture automatically segmentation which is in control of threshold and boundary is adopted, combing threshold segmentation principle with shapes of vertical fracture , we can segment and extract fracture images accurately.
The result of image segmentation will influence the accuracy of the parameters calculation directly. 1.1The automatic segmentation principle of threshold fracture The image segmentation is based on the principle of “The same kind of material, things or objects own the maximum probability with the same or similar grayscale or color”, so each pixel point in the image can be used to do segmentation.
