Chapter 40. Computer Vision on the GPU

James FungUniversity of Toronto

Computer vision tasks are computationally intensive and repetitive, and they often exceed the real-time capabilities of the CPU, leaving little time for higher-level tasks. However, many computer vision operations map efficiently onto the modern GPU, whose programmability allows a wide variety of computer vision algorithms to be implemented. This chapter presents methods of efficiently mapping common mathematical operations of computer vision onto modern computer graphics architecture.

Introduction

In some sense, computer graphics and computer vision are the opposites of one another. Computer graphics takes a numerical description of a scene and renders an image, whereas computer ...
