Extract depth using multiple focus levels
WebApr 28, 2024 · 3.2 Region-based depth feature descriptor. In order to extract the depth cue embedded in the focal stack at the super-pixel level, we propose a region-based depth feature descriptor by integrating the degree of defocusing over M focal stack images. The ideas behind the proposed RDFD originates from these two observations: (1) A set of … http://www0.cs.ucl.ac.uk/staff/N.Campbell/papers/eccv08_multi_hypo_dm.pdf

Answer EDF (extended depth of field) processing works by combining the best focused parts of a number of images taken at different focus levels into a composite image. To create an EDF image you must scan a region of interest using the multi-layer focus method.
