Flexible approach to image warping

This paper describes a novel approach to designing and applying spatial transformations to images, a technique that has only recently been exploited. The concept is to create and save the transformation as a look-up table (LUT) and then to use the look-up table to control the image resampling. This approach is very flexible; it is even amenable to transformations that cannot be implemented using classical approaches.
