	abstract =	{We present an algorithm for retrieval by spatial
	similarity of symbolic images. The proposed algorithm is based on
	graph-matching and is invariant to scaling, rotation and translation,
	recognizes multiple rotation variants and can deal with multiple
	instances of a symbolic object in an image.

	It is particularly suitable for a query by sketch approach, in that it
	requires that at least objects in the query have to be present in the
	database image.

	Our approach is proposed in comparison with other two well-known
	algorithms. Peculiarities are analyzed and motivated. Results of a
	comparative evaluation on a test dataset of symbolic images are
	presented and discussed.},
