	Lightness Perception and Lightness Illusions by Edward H. Adelson This interactive tutorial demonstrates how lightness illusions provide insights into the underlying mechanisms of the human visual system.
	Fundamentals of Image Processing by Hany Farid The fundamentals of image processing are presented within a unifying linear algebraic framework. Topics in 1-D and 2-D signal/image processing are covered.

Demonstrations

	Layered Image Representation by John Y.A. Wang Describes a system for representing moving images with sets of overlapping layers.
	Plenoptic Camera by John Y.A. Wang A novel single lens camera that captures 3-D information.
	Perceptual Grouping and Gelatinous Ellipses by Yair Weiss Some demonstrations of the ambiguity of motion and our visual system's use of perceptual grouping in order to resolve this ambiguity.

Illusions

	Checkerboard Illusion by Edward H. Adelson Demonstrates how the visual system uses several tricks to determine where shadows are and how to compensate for them.
	Munker-White Illusion by Bart Anderson An illusion that demonstrates how the visual system can experience great lighting differences even when two elements are actually the same color.
