TL;DR
A new post-processing step is presented to enhance the resolution of range images, using one or two registered and potentially high-resolution color images as reference and iteratively refine the input low-resolution range image in terms of both its spatial resolution and depth precision.
Abstract
We present a new post-processing step to enhance the resolution of range images. Using one or two registered and potentially high-resolution color images as reference, we iteratively refine the input low-resolution range image, in terms of both its spatial resolution and depth precision. Evaluation using the Middlebury benchmark shows across-the-board improvement for sub-pixel accuracy. We also demonstrated its effectiveness for spatial resolution enhancement up to 100 times with a single reference image.

Bilateral filtering for gray and color images
7,991 Citations2002Carlo Tomasi, Roberto Manduchi
In contrast with filters that operate on the three bands of a color image separately, a bilateral filter can enforce the perceptual metric underlying the CIE-Lab color space, and smooth colors and preserve edges in a way that is tuned to human perception.
