	abstract =	{This thesis presents new methods for integrating spatial
	and feature information in order to improve systems for image
	retrieval, analysis and compression. In particular, this thesis
	develops and demonstrates an integrated spatial and feature query
	paradigm for image retrieval, a general framework for extracting
	spatially localized features from images using histogram and binary set
	back-projections, a system for image compression and analysis based
	upon a joint-adaptive space and frequency (JASF) graph, and a
	representation of texture based upon spatial-frequency energy
	histograms. 

	These techniques are similar in their exploitation of images as
	two-dimensional, non-stationary signals. The visually important
	information within images is often confined to spatially localized
	regions, or is represented by the spatial arrangements of these
	regions. By developing processes that analyze and represent images in
	this way, we improve our capabilities to develop powerful content-based
	image retrieval and image compression systems. 

	This thesis examines several image system applications, such as image
	and video storage and retrieval, content-based image query, adaptive
	image compression and image analysis. We demonstrate that by using the
	proposed integrated spatial and feature approaches, we improve image
	system performance in each application over non-integrated methods.},
