... extract fractures. Pixels are divided based on the maximum inter-class variance method so that the maximum variance of different categories can effectively reduce the noise points in the image after fractures extraction (Wang, 2006). Through the Beamlet transform, the core image after threshold...

... that can be viewed as a modern form of the particle tracking technique, where sub-image movements are traced. For example, suppose that an image is taken for DIC processing and it has the size of 100 × 100 pixels (Fig. 2). The matching process is the identification of a target between the two images...
