Concrete Image Segmentation Based on Multiscale Mathematic Morphology Operators and Otsu Method

<div>Comparison of segmentation results for CT concrete images by three threshold methods. (a)–(c) denote the original C30 CT images. (d)–(f) denote the original C40 CT images. From left to right column: results of original CT images, two-mode algorithm, iterative algorithm, and Otsu method.</div>
