Warping and Morphing

Abstract

This chapter studies topological filters designed to change the shape of the objects of an image. This process is called deformation or warping, and therefore we talk about warping filters Together with amplitude filters, which change the image’s color information, warping filters can be used to create a transition between images of different objects, in a technique known as morphing Warping and morphing filters are important in many applications, from the correction of preexisting image distortions to the creation of special effects in the entertainment industry.
