GENERATING A DEPTH MAP FROM A TW0-DIMENSIONAL SOURCE IMAGE FOR STEREOSCOPIC AND MULTIVIEW IMAGING

摘要

Depth maps are generated from a monoscopic source images and asymmetricallysmoothed to anear-saturation level. Each depth map contains depth values focused on edgesof local regions in the sourceimage. Each edge is defined by a predetermined image parameter having anestimated value exceeding apredefined threshold. The depth values are based on the correspondingestimated values of the imageparameter. The depth map is used to process the source image by a depth imagebased renderingalgorithm to create at least one deviated image, which forms with the sourceimage a set of monoscopicimages. At least one stereoscopic image pair is selected from such a set foruse in generating differentviewpoints for multiview and stereoscopic purposes, including still and movingimages.
