	abstract =	{In their paper entitled ``Pyramid-Based Texture
	Analysis/Synthesis'' [4], Heeger and Bergen present an algorithm for
	generating synthetic copies of stochastic textures. Based on a
	self-inverting oriented bandpass pyramid and a histogram matching
	technique, the process is tantalizing both for the results it produces
	and for its intrinsic simplicity. Given a texture sample, either
	grayscale or color, the algorithm can synthesize as much of it as
	desired. 

	Here, we present an implementation and discussion of Heeger and
	Bergen's algorithm. The focus is on the use of the algorithm for
	texture generation (i.e., as opposed to texture analysis). An attempt
	is made to elaborate on the key components of the design, especially in
	areas covered briefly in [4]. In particular, details are provided about
	the steerable pyramid, and the iterative histogram matching that forms
	the core of the process. Also presented are a number of textures
	generated by the algorithm, including several produced from the samples
	used in [4] for comparison.},
