Digital Image Warping

By George Wolberg

Book Overview

This best-selling, original text focuses on image reconstruction, real-time texture mapping, separable algorithms, two-pass transforms, mesh warping, and special effects. The text, containing all original material, begins with the history of the field and continues with a review of common terminology, mathematical preliminaries, and digital image acquisition. Later chapters discuss equations for spatial information, interpolation kernels, filtering problems, and fast-warping techniques based on scanline algorithms.

Customer Reviews

Good general overview

I read Wolberg's book after writing my own morph program, I wish I had read it beforehand. It gives a good overview of warping techniques, clearly differentiates between forward and inverse mapping, and gives by far the best description of Doug Smythe's morphing program that exists. People who complain about a lack of code samples are whiners. Nothing in this book is complex in the least, and the implementation of any of the algorithms in it is pretty straightforward.

Classic reference, unfortunately out of print

George Wolberg invented the digital image warping techniques that were used to make the special effects in Willow and The Abyss. "Digital Image Warping" is the classic reference for fast image warping. It is the first place I went to learn how to speed up this operation. Unfortunately, this book is now out of print, but it is still available directly from the author. As the previous reviewer indicates, this is not a programming text; but it is clearly written and explores a wide variety of image warping techniques, clearly describing highly efficient algorithms for each. This book is without peer for this important class of image operations.
