A comprehensive survey of thinning methodologies is presented. A wide range of thinning algorithms, including iterative deletion of pixels and nonpixel-based methods, is covered. Skeletonization algorithms based on medial axis and other distance transforms are not considered. An overview of the iterative thinning process and the pixel-deletion criteria needed to preserve the connectivity of the image pattern is given first. Thinning algorithms are then considered in terms of these criteria and…

Comparative Survey of Thinning Algorithms

TLDR
The goal of this paper is to introduce the most common thinning methodologies and propose a method to evaluate their performance, especially in the field of signature recognition, and take into account various properties of a thinned skeleton and compares them to those of an ideal reference image.

Depth-based thinning: A new non-iterative skeletonization algorithm for 2D digital images

TLDR
An improved thinning algorithm that uses the depth of each point to find the deepest points, only considers the deepestpoints and its neighboring points to determine the point can be deleted and the thinning processing time is decreased, and the skeleton is smooth, clear and continuous.

A Sequential Thinning Algorithm For Multi-Dimensional Binary Patterns

TLDR
A sequential algorithm that is very easy to understand and modify based on application to perform the thinning of multi-dimensional binary patterns to prove the validity of the procedure.

TLDR
The authors present a novel approach to detecting ambiguous regions in a thinned image which uses the reconstructability properties of appropriate thinning algorithms to reverse the thinning process and automatically detect those pixels which may have resulted from more then one stroke in the image.

TLDR
Two new iterative algorithms for thinning binary images are proposed by using two operations: edge detection and subtraction and repeatedly conditionally eroding the pixels until a one pixel thick pattern is obtained.
