Abstract

Skeletonization on binary image is a process for reducing foreground regions to a skeletal remnant, which largely preserves the original region’s connectivity. An algorithm for skeletonization based on k-nearest-neighbors is proposed in this paper. Instead of the fixed 8-neighborhood approach, which is the most common in the thinning field, our algorithm implements skeletonization based on k-nearest-neighbors. The method mainly consists of two stages: raw skeleton extraction and a novel thinning for post-processing. Extensive experiments are conducted and results show that the skeleton extracted by our method is precise, clean, and much smoother than the previous works.
