Extract depth using multiple focus levels

WebFeb 14, 2024 · In computer vision, depth is extracted from 2 prevalent methodologies. Namely, depth from monocular images (static or sequential) or depth from stereo images by exploiting epipolar geometry. This post will focus on giving readers a background into depth estimation and the problems associated with it. http://www0.cs.ucl.ac.uk/staff/N.Campbell/papers/eccv08_multi_hypo_dm.pdf
