Edge-guided depth map enhancement
2016 23rd International Conference on Pattern Recognition (ICPR), 2016Low-cost depth sensing devices, such as Microsoft Kinect, can only produce noisy depth maps that are mis-aligned with color images, and even contain many holes. Even though the coupled high quality color images contain rich information which can be exploited to enhance the depth maps, the redundant color edges often introduce incorrect depth edges in ...

Coordinate systems are presented for fast 3-D transformations of complex surfaces, such as the depth maps produced by a laser camera or by a viewing algorithm. It is shown that these coordinate systems are natural for calculation on depth maps and correspond to a differential geometry approach of the problem.

Depth maps are becoming a readily available commodity of the stereo pipeline. We propose to make use of this new free information to improve a key step of postproduction that is matting. We extend the work of Levin et al on closed form matting to introduce two new depth-aware techniques. First we explore how depth can be used as an extra channel in the

Computer determination of depth maps
Computer Graphics and Image Processing, 1973The research in support of the integrated robot project Lit the Jet Propulsion Laboratory is partially directed towards the problem of visual perception by computer. It is anticipated that the autonomous behavior of the robot will be predicated on the feedback obtained by an analysis of the environment.

Depth mapping of time horizons
SEG Technical Program Expanded Abstracts 1998, 1998This maximum depth principle for computing horizon depths is a dual to Fermat’s minimum time principle for computing traveltimes. With this proposition a reflecting horizon is mapped from time to depth by finding the envelope of all possible depths that can be computed with the velocity model.

Super-Resolution for Depth Maps
2014One of the major limitations of depth cameras is the relatively low resolution, which is addressed in this chapter. The resolution of color images easily reaches mega-pixels in multi-camera 2D/3D setups or for the 2D/3D MultiCam (cf. Section 3.2). However, the resolution of current PMD chips is 160×120 or 200×200 pixels.
