Low Complexity H.265/HEVC Coding Unit Size Decision for a Videoconferencing System

Cybernetics and Information Technologies, 2015
With the development of Internet and video capture techniques, videoconferencing becomes still more popular. However, with the increased size of the video resolution, the volume of the raw videoconferencing video data increases dramatically.

Low Complexity HEVC Encoder for Visual Sensor Networks

Sensors, 2015
Visual sensor networks (VSNs) can be widely applied in security surveillance, environmental monitoring, smart rooms, etc. However, with the increased number of camera nodes in VSNs, the volume of the visual information data increases significantly, which

Fast depth intra coding based on texture feature and spatio‐temporal correlation in 3D‐HEVC

IET Image Processing, 2021
To alleviate the computation burden of the depth intra coding in 3D‐HEVC, a complexity reduction scheme based on texture feature and spatio‐temporal correlation is proposed.

Exploring Measurement through Coding: Children’s Conceptions of a Dynamic Linear Unit with Robot Coding Toys

Education Sciences, 2022
Programming activities have the potential to provide a rich context for exploring measurement units in early elementary mathematics. This study examines how a small group of young children (ages 5–6) express their emergent conception of a dynamic linear ...

Content analysis: What are they talking about? [PDF]

, 2006
Quantitative content analysis is increasingly used to surpass surface level analyses in Computer-Supported Collaborative Learning (e.g., counting messages), but critical reflection on accepted practice has generally not been reported.

Polynomial time algorithms for multicast network code construction [PDF]

, 2005
The famous max-flow min-cut theorem states that a source node s can send information through a network (V, E) to a sink node t at a rate determined by the min-cut separating s and t.

Zebrafish capable of generating future state prediction error show improved active avoidance behavior in virtual reality

Nature Communications, 2021
Using a closed-loop virtual reality system for fish, the authors show that zebrafish are capable of assigning rules to the scenery they see, and of generating a state prediction error by comparing reality with a prediction derived from an internal model.

Quantum Channel Capacities Per Unit Cost [PDF]

, 2018
Communication over a noisy channel is often conducted in a setting in which different input symbols to the channel incur a certain cost. For example, for bosonic quantum channels, the cost associated with an input state is the number of photons, which is
