Extracting ridges of topographic surfaces using scanline algorithm

The ridge/valley-like structures of a topographic surface have been extensively studied in image processing to obtain useful skeleton-like shape descriptors. In this paper, we propose a novel method that rapidly constructs the graph representation of the skeletons of the curvilinear objects such as...
