Computational photography

Abstract

Stitching multiple images into wide field of view panoramas, which we covered in Chapter 9, allows us create photographs that could not be captured with a regular camera. This is just one instance of computational photography, where image analysis and processing algorithms are applied to one or more photographs to create images that go beyond the capabilities of traditional imaging systems. Some of these techniques are now being incorporated directly into digital still cameras. For example, some of the newer digital still cameras have sweep panorama modes and take multiple shots in low-light conditions to reduce image noise.
