Proceedings of the 25th annual conference on Computer graphics and interactive techniques - SIGGRAPH '98, 1998 In this paper we present a set of efficient image based rendering methods capable of rendering multiple frames per second on a PC. The first method warps Sprites with Depth representing smooth surfaces without the gaps found in other techniques. A second method for more general scenes performs warping from an intermediate representation called a ...

Optics Express, 2020 Single-photon lidar (SPL) is a promising technology for depth measurement at long range or from weak reflectors because of the sensitivity to extremely low light levels. However, constraints on the timing resolution of existing arrays of single-photon avalanche diode (SPAD) detectors limit the precision of resulting depth estimates.

Depth-SIMS: Semi-Parametric Image and Depth Synthesis
2022 International Conference on Robotics and Automation (ICRA), 2022 In this paper we present a compositing image synthesis method that generates RGB canvases with well aligned segmentation maps and sparse depth maps, coupled with an in-painting network that transforms the RGB canvases into high quality RGB images and the sparse depth maps into pixel-wise dense depth maps.

Sparse Representations-based depth images quality assessment
Visual Informatics, 2021 The conventional 2D metrics can be used for measuring the quality of depth maps, but none of them is considered to be efficient and is not accurate when used for evaluating 3D quality.

Exploring depth information for head detection with depth images [PDF]
2016 13th IEEE International Conference on Advanced Video and Signal Based Surveillance (AVSS), 2016 Head detection may be more demanding than face recognition and pedestrian detection in the scenarios where a face turns away or body parts are occluded in the view of a sensor, but locating people is needed. In this paper, we introduce an efficient head detection approach for single depth images at low computational expense.

Underwater Depth Estimation for Spherical Images
Journal of Robotics, 2021 This paper proposes a method for monocular underwater depth estimation, which is an open problem in robotics and computer vision. To this end, we leverage publicly available in-air RGB-D image pairs for underwater depth estimation in the spherical domain

Dynamic Pose Estimation Using Multiple RGB-D Cameras
Sensors, 2018 Human poses are difficult to estimate due to the complicated body structure and the self-occlusion problem. In this paper, we introduce a marker-less system for human pose estimation by detecting and tracking key body parts, namely the head, hands, and ...
