  abstracttext	= {This article shows how the interactive segmentation tool
		  termed "Active Paintbrush" and a fully automatic region
		  merging can both be based on the theoretical framework of
		  contraction kernels within irregular pyramids instead of
		  their own, specialized data structures. We introduce
		  "continous pyramids" in which we purposely drop the common
		  requirement of a fixed reduction factor between successive
		  levels, and we show how contraction kernels can be
		  annotated for a fast navigation of such pyramids. Finally,
		  we use these concepts for improving the integration of the
		  automatic region merging and the interactive tool.}
