A Hu moment invariant as a shape circularity measure
In this paper we propose a new circularity measure which defines the degree to which a
shape differs from a perfect circle. The new measure is easy to compute and, being area …

Articulation-invariant representation of non-planar shapes
R Gopalan, P Turaga, R Chellappa - … Crete, Greece, September 5-11, 2010 …, 2010 - Springer
Given a set of points corresponding to a 2D projection of a non-planar shape, we would like
to obtain a representation invariant to articulations (under no self-occlusions). It is a …

An integrated segmentation and shape‐based classification scheme for distinguishing adenocarcinomas from granulomas on lung CT
Purpose Distinguishing between benign granulmoas and adenocarcinomas is confounded
by their similar visual appearance on routine CT scans. Unfortunately, owing to the inability …

Measuring elongation from shape boundary
M Stojmenović, J Žunić - Journal of Mathematical Imaging and Vision, 2008 - Springer
Shape elongation is one of the basic shape descriptors that has a very clear intuitive
meaning. That is the reason for its applicability in many shape classification tasks. In this …

Shape ellipticity from Hu moment invariants
In this paper we derive an explicit formula which uses the first two Hu moment invariants to
compute a shape ellipticity measure, ie to evaluate how much a planar shape differs from an …
