Interface  Description 

ThinningSkeleton 
Common 2dimensional skeletonization algorithm of binary matrices, based on ≤8 thinning steps,
corresponding to all or some from 8 directions with the step 45 degree.

Class  Description 

ApertureBasedSkeletonPixelClassifier 
A skeletal implementation of the
SkeletonPixelClassifier abstract class,
minimizing the effort required to implement its abstract methods. 
BasicSkeletonPixelClassifier2D 
Ready classifier of pixel of 2dimensional
thinning skeletons . 
ErodingSkeleton 
The simplest algorithm of multidimensional skeletonization of binary matrices, based on sequential
erosions of the matrix by some small pattern. 
OctupleThinningSkeleton2D 
Algorithm of 2dimensional skeletonization of binary matrices based on 8 thinning steps,
corresponding to 8 directions with the step 45 degree, based on analysis of 3x3 aperture.

Quadruple3x5ThinningSkeleton2D 
Algorithm of 2dimensional skeletonization of binary matrices based on 4 thinning steps,
corresponding to 4 directions with the step 90 degree, based on analysis of 3x5 aperture.

SkeletonPixelClassifier 
Classifier of pixels of skeletons (bit matrices, generated by skeletonization algorithms),
separating them into "nodes", "branch pixels" and other groups.

SkeletonScanner 
Scanner of skeletons (bit matrices, generated by skeletonization algorithms), allowing
to scan a skeleton, find and traverse all its structural elements like nodes and branches.

StrongQuadruple3x5ThinningSkeleton2D 
Stronger version of
Quadruple3x5ThinningSkeleton2D skeletonization algorithm. 
WeakOctupleThinningSkeleton2D 
Weaker version of
OctupleThinningSkeleton2D skeletonization algorithm. 
Enum  Description 

SkeletonPixelClassifier.AttachmentInformation 
Style of interpretation of nonnegative results while detecting pixel types of the skeleton.

Algorithms of skeletonization of binary
2 or ndimensional AlgART matrices
.
This package contains several skeletonization classes,
implementing IterativeArrayProcessor
interface:
ErodingSkeleton
,WeakOctupleThinningSkeleton2D
,OctupleThinningSkeleton2D
,Quadruple3x5ThinningSkeleton2D
,StrongQuadruple3x5ThinningSkeleton2D
.Every iteration of these iterative processors makes all particles (matrix areas, filled by unit elements)
little smaller, but saves connectivity of particles
(excepting ErodingSkeleton
, which does not provide saving connectivity).
After finishing all iterations, the resulting matrix, called skeleton,
usually contains thin "lines", called skeleton branches, which connect different
skeleton nodes (points of intersection of these lines).
The class SkeletonScanner
allows to detect and analyse
the structure of skeleton.
