1. A method for adaptive depth map reconstruction, the method comprising: receiving a mask identifying at least one region of interest (ROI) in a scene; according to said mask, spatially changing an operative resolution of a depth map reconstruction module used to reconstruct a depth map of said scene; using a range-sensing device on said scene; and reconstructing, by said depth map reconstruction module, a depth map of said scene, said reconstructed depth map being such that a spatial resolution R ROI in said ROI is higher relative to a spatial resolution R other of scene locations not associated with said ROI, where: R other <R ROI .
