Methods, devices and computer program products for gradient based depth reconstructions with robust statistics

摘要

A method of generating a refined depth map for a three-dimensional (3D) model of an object is described. The method may include may include warping a set of target images, resulting in warped target images, wherein the set of target images is selected from the plurality of images; determining a difference between each warped target image and a reference image, wherein the reference image is from the plurality of images; determining, for each warped target image, an alpha mask comprising per-pixel weights; and updating an initialized depth map based on alpha mask, resulting in the estimated depth map. Related systems, devices and computer program products are also described.
