3.Shape Descr iptors

Centroids (Center of Mass)

3.2 Statistical moments:

Useful for describing the shape of boundary segments (or other curves)

Suitable for describing the shape of convex deficiencies

The histogram of the function (segment curve) can also be used for calculating moments

2nd moment gives spread around mean (variance)

3rd moment gives symmetry around mean (skewness)
