imShapes

The imShapes module provides functions for generating binary images representing geometric 2D / 3D shapes (disks, squares, balls, ellipsoids, cylinders...). It requires the matGeom library, as well as the imFilters module.

Its typical usage is to test and validate functions written in the imMeasures, imMinkowski or imGeodesics modules.
