Hand–Object Pose Estimation Based on Anchor Regression from a Single Egocentric Depth Image [PDF]

Sensors
To precisely understand the interaction behaviors of humans, a computer vision system needs to accurately acquire the poses of the hand and its manipulated object. Vision-based hand–object pose estimation has become an important research topic.

Exemplar-based image completion using image depth information. [PDF]

PLoS ONE, 2018
Image completion techniques are required to complete missing regions in digital images. A key challenge for image completion is keeping consistency of image structures without ambiguity and visual artifacts. We propose a novel method for image completion

DTS-Depth: Real-Time Single-Image Depth Estimation Using Depth-to-Space Image Construction

Sensors, 2022
As most of the recent high-resolution depth-estimation algorithms are computationally so expensive that they cannot work in real time, the common solution is using a low-resolution input image to reduce the computational complexity.
