CHAPTER 12

Image Processing Techniques

A comprehensive treatment of image processing techniques is beyond the scope of this book. However, since image processing is such a powerful tool, even a subset of image processing techniques can be useful, and is a powerful adjunct to computer graphics approaches. Some of the more fundamental processing algorithms are described here, along with methods for accelerating them using the OpenGL pipeline.

12.1 OpenGL Imaging Support

Image processing is an important component of applications used in the publishing, satellite imagery analysis, medical, and seismic imaging fields. Given its importance, image processing functionality has been added to OpenGL in a number of ways. A bundle of extensions targeted ...
