Rate-Perception Optimized Preprocessing for Video Coding
Chengqian Ma, Zhiqiang Wu, Chunlei Cai +5
In the past decades, lots of progress have been done in the video compression field including traditional video codec and learning-based video codec. However, few studies focus on…
Convolutional Block Design for Learned Fractional Downsampling
Li-Heng Chen, Christos G. Bampis, Zhi Li +2
The layers of convolutional neural networks (CNNs) can be used to alter the resolution of their inputs, but the scaling factors are limited to integer values. However, in many imag…
Encoding Bitrate Optimization Using Playback Statistics for HTTP-based Adaptive Video Streaming
Chao Chen, Yao-Chung Lin, Anil Kokaram +1
HTTP video streaming is in wide use to deliver video over the Internet. With HTTP adaptive steaming, a video playback dynamically selects a video stream from a pre-encoded represen…
Rate Adaptation and Admission Control for Video Transmission with Subjective Quality Constraints
Chao Chen, Xiaoqing Zhu, Gustavo de Veciana +2
Adapting video data rate during streaming can effectively reduce the risk of playback interruptions caused by channel throughput fluctuations. The variations in rate, however, also…
Modeling the Time-varying Subjective Quality of HTTP Video Streams with Rate Adaptations
Chao Chen, Lark Kwon Choi, Gustavo de Veciana +3
Newly developed HTTP-based video streaming technologies enable flexible rate-adaptation under varying channel conditions. Accurately predicting the users' Quality of Experience (Qo…
A Markov Decision Model for Adaptive Scheduling of Stored Scalable Videos
Chao Chen, Robert W. Heath, Alan C. Bovik +1
We propose two scheduling algorithms that seek to optimize the quality of scalably coded videos that have been stored at a video server before transmission.} The first scheduling a…
