A Novel Algorithm for Skeleton Extraction From Images Using

vector-based methods (i e topological graphs and com-putational geometry) to extract skeletons of input binary images Our results show the effectiveness of our ap-proach and algorithms based on graphs and computa-tional geometry (i e visibility polygon kernel and lo-cal kernel [16]) 2 Approach and Algorithms

Is there a hierarchically optimal skeleton network of polygons?
Skeleton is an important 1-D descriptor of polygon and a useful tool for advanced geometric algorithms. However the skeleton that most existing algorithms investigated is the longest one, which is not intended in all circumstances. This paper proposes an algorithm for extracting hierarchically optimal skeleton network of polygons.
Is there an algorithm for extracting the skeleton network of polygons?
However the skeleton that most existing algorithms investigated is the longest one, which is not intended in all circumstances. This paper proposes an algorithm for extracting hierarchically optimal skeleton network of polygons.
Why is topological graph-based skeleton extraction important?
Topological graph-based skeleton extraction has clear and intuitive advantages for further shape analy-sis, and also for automation of effective feature extrac-tion for machine learning algorithms for image analysis.
How do we extract a straight skeleton?
To solve the first problem, we extract a straight skeleton by propagating the silhouette polygon inward, and we accelerate the algorithm by finding a concise shape approximation through DP simplification, a novel BoundedDP algorithm is then used to transfer the straight skeleton into the animatable bone skeleton.
