Estimation of Sandstone Permeability with SEM Images Based
- Image binarization transforms a SEM image into a binary image. The pore information such as area and perimeter of irregular pores in the image is retained, which is a basis for further analysis and calculation. Global histogram-based binary algorithm is an effective method to solve this problem that can retain all information of the pore. It includ...
