1. A method for representing a class of objects, comprising:
- acquiring a set of samples for the objects in the class, there being one sample for each object, and each sample includes a plurality of data values representing characteristics of the object;
grouping the samples into subsets such that each subset intersects at least one other subset;
determining, for each subset, a low-dimensional subset parameterization; and
averaging nullspaces of the low-dimensional subset parameterizations to obtain a matrix having a nullspace containing a low-dimensional representation of the class of objects.

Abstract
A method represents a class of objects. A set of samples for the objects in the class is acquired, there being one sample for each object, and each sample includes a plurality of data values representing characteristics of the object. The samples are grouped into subsets such that each subset intersects at least one other subset. For each subset, a low-dimensional parameterization is determined. Nullspaces of the low-dimensional parameterizations are averaged to obtain a matrix whose nullspace contains a low-dimensional representation of the class of objects.
