Region2DSkeletonAnalyzer

API

This operator calculates for a set of regions in a given image the region skeletons and subsequently extracts some feature measures from the skeletons. Measures currently implemented are, e.g.,

The distance of a branch endpoint to the background can be interpreted as the radius of a maximal circle located at the branch endpoint and touching the boundary of the region. This radius can be regarded as an estimate for the local curvature of the region boundary, hence, the average radius of all branch endpoints yield a measure for the 'roughness' of the boundary, i.e. how much the boundary 'curves' on average.
