Delivering real-time video over the Internet is an important component of many Internet
multimedia applications. Transmission of real-time video has bandwidth, delay, and loss …

Abstract Multimedia oriented Internet of Things (IoT) enables pervasive and real-time
communication of video, audio and image data among devices in an immediate …

Rate control is a useful tool for video coding, especially in real-time communication
applications. Most of existing rate control algorithms are based on the RQ model, which …

An important motivation for the development of the emerging H. 263+ and MPEG-4 coding
standards is to enhance the quality of highly compressed video for two-way, real-time …

In this paper, an efficient rate-control scheme for H. 264/AVC video encoding is proposed.
The redesign of the quantization scheme in H. 264/AVC results in that the relationship …

This paper presents a scalable rate control (SRC) scheme based on a more accurate
second-order rate-distortion model. A sliding-window method for data selection is used to …

We first develop a rate-distortion (RD) model for DCT-based video coding incorporating the
macroblock (MB) intra refreshing rate. For any given bit rate and intra refreshing rate, this …

Mobile devices performing video coding and streaming over wireless and pervasive
communication networks are limited in energy supply. To prolong the operational lifetime of …

Image segmentation is a classic subject in the field of image processing and also is a
hotspot and focus of image processing techniques. With the improvement of computer …

Video streaming usage has seen a significant rise as entertainment, education, and
business increasingly rely on online video. Optimizing video compression has the potential …
