# Skeletonization algorithm

Oct 25, 2016 · The image processing **algorithm** we developed is structured in three main steps before the **skeletonization** procedure is applied: (1) image preprocessing, (2) morphological dilation (3) and thresholding and segmentation. Figure 2 shows the steps of the **algorithm** before **skeletonization**, which will be explained in more detail below..

The **skeletonization** **algorithm** has a time complexity which is linear in the amount of voxels, and can be easily parallelized. The relation of the IMA skeleton to the usual definition in terms of centers of maximal disks is discussed. (Show Context) Combined Boundary-Medial Shape Description of Variable Biological Objects..

In this research, we study the problem of font image **skeletonization** using an end-to-end deep adversarial network, in contrast with the state-of-the-art methods that use mathematical.

. Morphological **Skeletonization** can be considered as a controlled erosion process. This involves shrinking the image until the area of interest is 1 pixel wide. This can allow quick and accurate image processing on an otherwise large and memory intensive operation. A great example of using **skeletonization** on an image is processing fingerprints..

**Skeletonization** refers to the final stage of decomposition, during which the last vestiges of the soft tissues of a corpse or carcass have decayed or dried to the point that the skeleton is exposed. By the end of the **skeletonization** process, all soft tissue will have been eliminated, leaving only disarticulated bones.

Jan 01, 2015 · Abstract. The skeleton of a binary object can be considered as an alternative to the object itself; it describes the object in a simple and compact manner that preserves the object topology.
