WebConclusions and future work. This paper proposed a novel noise removal method for binary images of concrete cracks. The method, dubbed Skele-Marker, thins a noisy crack image to a skeleton, before using a morphological reconstruction to remove all elements in the noisy image that do not intersect with the skeleton.
