Information

CS 4475 (3-0-3): Computational Photography – (Instructor: Irfan Essa) – This class explores perceptual and technical aspects of pictures, and more precisely the capture and depiction of reality on a 2D medium. The scientific, perceptual, and artistic principles behind image-making will be emphasized. Topics include the relationship between pictorial techniques and the human visual system; intrinsic limitations of 2D representations and their possible compensations; and technical issues involving depiction. Technical aspects of image capture and rendering, and exploration of how such a medium can be used to its maximum potential, will be examined. Students are strongly encouraged (not required) to bring their digital cameras and a laptop to facilitate experiments.
