A Tri-Dynamic Preprocessing Framework for UGC Video Compression

ICASSP 2024accepted

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 characteristics compared to traditional encoding test videos. This variance challenges the effectiveness of data-driven machine lear…

Region-Adaptive Video Sharpening Via Rate-Perception Optimization

ICASSP 2024accepted

Sharpening is a widely adopted video enhancement technique. However, uniform sharpening intensity ignores texture variations, degrading video quality. Sharpening also increases bitrate, and there’s a lack of techniques to optimally allocate these additional bits across diverse regions. Thus, this pa…

Self-Asymmetric Invertible Network for Compression-Aware Image Rescaling

AAAI 2023technical

High-resolution (HR) images are usually downscaled to low-resolution (LR) ones for better display and afterward upscaled back to the original size to recover details. Recent work in image rescaling formulates downscaling and upscaling as a unified task and learns a bijective mapping between HR and L…
