	abstract =	{We describe a method for shape-based image database search
	that uses deformable prototypes to represent categories. Rather than
	directly comparing a candidate shape with all shape entries in the
	database, shapes are compared in terms of the types of nonrigid
	deformations (differences) that relate them to a small subset of
	representative prototypes. To solve the shape correspondence and
	alignment problem, we employ the technique of modal matching, an
	information-preserving shape decomposition for matching, describing,
	and comparing shapes despite sensor variations and nonrigid
	deformations. In modal matching, shape is decomposed into an ordered
	basis of orthogonal principal components. We demonstrate the utility of
	this approach for shape comparison in 2-D image databases.},
