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

Beyond Image to Depth: Improving Depth Prediction using Echoes [PDF]

2021 IEEE/CVF Conference on Computer Vision and Pattern Recognition (CVPR), 2021
We address the problem of estimating depth with multi modal audio visual data. Inspired by the ability of animals, such as bats and dolphins, to infer distance of objects with echolocation, some recent methods have utilized echoes for depth estimation.

DEEP LEARNING FOR MONOCULAR DEPTH ESTIMATION FROM UAV IMAGES [PDF]

ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2020
Depth is an essential component for various scene understanding tasks and for reconstructing the 3D geometry of the scene. Estimating depth from stereo images requires multiple views of the same scene to be captured which is often not possible when ...

Selective rendering for efficient ray traced stereoscopic images [PDF]

, 2009
Depth-related visual effects are a key feature of many virtual environments. In stereo-based systems, the depth effect can be produced by delivering frames of disparate image pairs, while in monocular environments, the viewer has to extract this depth ...

Scene Recognition Based on Privilege Information and Attention Mechanism [PDF]

Zhengzhou Daxue xuebao. Gongxue ban, 2021
In the scene recognition, RGB images present appearance information and depth image contains geometry information，which complement each other. In order to use the complementary information contained in the depth images and the RGB images in the test ...

Nanometric depth resolution from multi-focal images in microscopy [PDF]

, 2011
We describe a method for tracking the position of small features in three dimensions from images recorded on a standard microscope with an inexpensive attachment between the microscope and the camera.

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 ...
