	abstract =	{The capacity to retrieve images containing objects with
	shapes similar to a query shape is desirable in medical image
	databases.  We propose a similarity measure and an indexing mechanism
	for non-rigid comparison of shape which adds this capability to image
	databases.

	The (dis-)similarity measure is based on the observation that: (1) the
	geometry of the same organ in different subjects is not related by a
	strictly rigid transformation; and (2) the orientation of the organ
	plays a key role in comparing shape. We propose a similarity measure
	that computes a non-rigid mapping between curves and uses this mapping
	to compute oriented shape.

	We also show how KD-trees can index curves so that retrieval with our
	similarity measure is efficient. Experiments with real-world data from
	a database of magnetic resonance images are provided.},
