	abstract =	{We present a universal statistical model for texture
	images in the context of an overcomplete complex wavelet transform. The
	model is parameterized by a set of statistics computed on pairs of
	coefficients corresponding to basis functions at adjacent spatial
	locations, orientations, and scales. We develop an efficient algorithm
	for synthesizing random images subject to these constraints, by
	iteratively projecting onto the set of images satisfying each
	constraint, and we use this to test the perceptual validity of the
	model. In particular, we demonstrate the necessity of subgroups of the
	parameter set by showing examples of texture synthesis that fail when
	those parameters are removed from the set. We also demonstrate the
	power of our model by successfully synthesizing examples drawn from a
	diverse collection of artificial and natural textures.},
