Paper Abstract

A method for recovering a depth map from an active focus analysis is presented. A sharpness map can be calculated for many small regions in an image using a Gaussian pyramid to sum the output of a Laplacian. The depth of each region can be recovered by examining the sharpness map over a range of focal positions. Real-time performance is achieved through hardware that computes Gaussian and Laplacian pyramids.
