Optimized viewport‐adaptive 360‐degree video streaming

open access: yesCAAI Transactions on Intelligence Technology, 2021
Because of the rapid growth of head‐mounted displays and 5G networking deployment, 360‐degree video has become increasingly popular. To generate the real experience of a virtual environment, 360‐degree videos require an ultrahigh resolution and frame ...

Biosynthetic Plastics as Tunable Elastic and Visible Stent with Shape‐Memory to Treat Biliary Stricture

open access: yesAdvanced Science, Volume 10, Issue 29, October 17, 2023., 2023
A biodegradable helical stent with shape memory and self‐expanding effect is fabricated from biosynthetic P(3HB‐co‐4HB) with tunable stiffness for the first time. The stent successfully treats biliary stricture in porcine model. Abstract Common biliary tract is ≈4 mm in diameter to deliver bile from liver to small intestine to help digestion.

Robust Spatial-Temporal Motion Coherent Priors for Multi-View Video Coding Artifact Reduction

open access: yesIEEE Access, 2023
Multi-view video (MVV) data processed by three-dimensional (3D) video systems often suffer from compression artifacts, which can degrade the rendering quality of 3D spaces.

Quantitative imaging of vesicle–protein interactions reveals close cooperation among proteins

open access: yesJournal of Extracellular Vesicles, Volume 12, Issue 5, May 2023., 2023
Abstract Membrane‐bound vesicles such as extracellular vesicles (EVs) can function as biochemical effectors on target cells. Docking of the vesicles onto recipient plasma membranes depends on their interaction with cell‐surface proteins, but a generalizable technique that can quantitatively observe these vesicle–protein interactions (VPIs) is lacking ...

Denoising and Inpainting for Point Clouds Compressed by V-PCC

open access: yesIEEE Access, 2021
With the development of immersive video, the quality of compressed 3D content has become an important issue. Video-based Point Cloud Compression (V-PCC) is a popular compression method for point cloud sequences; it achieves the highest quality among MPEG

Recursive block splitting in feature-driven decoder-side depth estimation

open access: yesETRI Journal, 2022
This paper presents a study on the use of encoder-derived features in decoder-side depth estimation. The scheme of multiview video encoding does not require the transmission of depth maps (which carry the geometry of a three-dimensional scene) as only a ...

Optimal packetisation of MPEG-4 using RTP over mobile networks [PDF]

open access: yes, 2001
The introduction of third-generation wireless networks should result in real-time mobile video communications becoming a reality. Delivery of such video is likely to be facilitated by the realtime transport protocol (RTP).
