Relation to Vision

An important aspect of image processing is the relationship between the methods employed and how our visual system interprets them.  Although the processing done by the visual cortex of our brains is not completely understood, there has been a lot of progress made in the last two decades in understanding how this processing is done.  An important feature of the new wavelet-based methods in image processing that we study in this course is that they are highly correlated with similar processes within our visual system.   This feature is one reason that wavelet-based methods are rapidly becoming the standard approach in image processing, and we shall demonstrate their advantages over earlier (Fourier based) methods in this course.
