Segmentation of 3D micro-Computed Tomographic uCT) images of rock samples is essential for further Digital Rock Physics (DRP) analysis, however, conventional methods such as thresholding, watershed segmentation ...
Deep Convolutional Neural Networks (CNNs) have produced accurate pixelwise semantic segmentation results with natural images and μCT rock images, however, physical accuracy is not well documented. ...
Image segmentation techniques used in Digital Rock Physics (DRP) range from simple thresholding [59] to multi-step marker based methods [24, 3] . ...
