class BlobSpatialObject : public itk::PointBasedSpatialObject<TDimension, SpatialObjectPoint<TDimension>>

Spatial object representing a potentially amorphous object.

The BlobSpatialObject is a discretized representation of a “blob”, which can be taken to be an arbitrary, possibly amorphous shape. The representation is a list of the points (voxel centers) contained in the object. This can be thought of as an alternate way to represent a binary image.
