Review on mainstream method of skeleton pruning

Abstract

The technique of skeleton pruning was generally deployed after the skeletonization of the binary image for filtering unwanted branches caused by the boundary noise, which was a vital pre-processing method before analysis and recognition of the skeleton. It was still a challenging task since there were not standard measurements for distinct the noise branches and original structural branches. In the past decade, there were many approaches based on different perspective have emerged for trying tackle that problem. The review of the most 6 cited paper was conducted in this paper.
