Sketching a Gray Scale Pattern Based on Non-ridge Points Lowering Operation

摘要

Skeleton is important means in shape analysis and object recognition. Based on so-called "non-ridge points lowering operator", a novel and simple approach for grayscale pattern skeletonization is presented in this paper. This algorithm includes three main processing steps: a non-ridge points lowering step, a local bottom labeling step and an application dependent pruning step. Experiments on natural images and synthesis images show that the algorithm can get encouraged results for some kind of smoothing image.
