A Tri-Dynamic Preprocessing Framework for UGC Video Compression
Fei Zhao, Mengxi Guo, Shijie Zhao +3
In recent years, user generated content (UGC) has become the dominant force in internet traffic. However, UGC videos exhibit a higher degree of variability and diverse characterist…
A Preprocessing Framework for Video Machine Vision under Compression
Fei Zhao, Mengxi Guo, Shijie Zhao +3
There has been a growing trend in compressing and transmitting videos from terminals for machine vision tasks. Nevertheless, most video coding optimization method focus on minimizi…
Frequency-Assisted Adaptive Sharpening Scheme Considering Bitrate and Quality Tradeoff
Yingxue Pang, Shijie Zhao, Haiqiang Wang +3
Sharpening is a widely adopted technique to improve video quality, which can effectively emphasize textures and alleviate blurring. However, increasing the sharpening level comes w…
Adaptive High-Frequency Preprocessing for Video Coding
Yingxue Pang, Shijie Zhao, Junlin Li +1
High-frequency components are crucial for maintaining video clarity and realism, but they also significantly impact coding bitrate, resulting in increased bandwidth and storage cos…
Region-Adaptive Video Sharpening via Rate-Perception Optimization
Yingxue Pang, Shijie Zhao, Mengxi Guo +2
Sharpening is a widely adopted video enhancement technique. However, uniform sharpening intensity ignores texture variations, degrading video quality. Sharpening also increases bit…
Spatial Degradation-Aware and Temporal Consistent Diffusion Model for Compressed Video Super-Resolution
Hongyu An, Xinfeng Zhang, Shijie Zhao +2
Due to storage and bandwidth limitations, videos transmitted over the Internet often exhibit low quality, characterized by low-resolution and compression artifacts. Although video…
