Computer vision is becoming increasingly important in several industrial applications such as automated inspection, robotic manipulations and autonomous vehicle guidance. These tasks are performed in a 3-D world and it is imperative to gather reliable information on the 3-D structure of the scene. This book is about passive techniques for depth recovery, where the scene is illuminated only by natural light as opposed to active methods where a special lighting device is used for scene illumination. Passive methods have a wider range of applicability and also correspond to the way humans infer 3-D structure from visual images. Of the several methods used for depth recovery: depth from stereo, structure from motion, shape from shading, structure from focus and depth from defocus, this book concentrates on the problem of recovering depth from defocused images. The book presents several new approaches for computing the depth of a scene when multiple, defocused images are given. Both deterministic and statistical approaches are covered. The book includes chapters on the basic theory of recovering depth from defocused images and a chapter providing the necessary mathematical background on space-frequency representations of signals, the calculus of variations, and Markov random fields, which are used in the subsequent chapters. This book should prove to be a valuable reference for researchers in computer vision interested in passive methods for depth recovery.

Depth recovery is important in machine vision applications when a 3-dimensional structure must be derived from 2-dimensional images. This is an active area of research with applications ranging from industrial robotics to military imaging. This book provides the comprehensive details of the methodology, along with the complete mathematics and algorithms involved. Many new models, both deterministic and statistical, are introduced.
