Depth from defocus dfd

Weba measure of relative depth of each object in the scene. The notion described above is the main idea behind depth-from-defocus (DfD) techniques, which attempt to reconstruct a depth map of the scene using a set of photographs, referred to as the focal stack, which are each taken of the same scene with the camera set to different focal depths.
