[Compgeom-discuss] Measure of similarity between two shapes?

[William Flis]

I am looking for a quantitative measure as to how similar two shapes are to
each other. (2-D and 3-D shapes would suffice for me.)

One shape is the output of some physical process, and is described as an
image (photograph or computer plot, hence pixel data). The other is a
desired shape, defined by its boundary, which could be a circle/sphere or a
polygon.
