Accelerating Merge with Motion Vector Difference via Filter Difference Analysis for VVenC
Xinmin Feng, Shengyang Xu, Jianhua Chen +3
Merge with Motion Vector Difference (MMVD) is a key coding tool in Versatile Video Coding for improving motion prediction accuracy. However, its exhaustive search strategy imposes…
TVRN: Invertible Neural Networks for Compression-Aware Temporal Video Rescaling
Xinmin Feng, Li Li, Dong Liu +1
To fit diverse display and bandwidth constraints, high-frame-rate videos are temporally downscaled to low-frame-rate (LFR) and later upscaled, requiring joint optimization for effe…
ProGVC: Progressive-based Generative Video Compression via Auto-Regressive Context Modeling
Daowen Li, Ruixiao Dong, Ying Chen +3
Perceptual video compression leverages generative priors to reconstruct realistic textures and motions at low bitrates. However, existing perceptual codecs often lack native suppor…
An FPGA Implementation of Displacement Vector Search for Intra Pattern Copy in JPEG XS
Qiyue Chen, Yao Li, Jie Tao +3
Recently, progress has been made on the Intra Pattern Copy (IPC) tool for JPEG XS, an image compression standard designed for low-latency and low-complexity coding. IPC performs wa…
HPC: Hierarchical Point-based Latent Representation for Streaming Dynamic Gaussian Splatting Compression
Yangzhi Ma, Bojun Liu, Wenting Liao +3
While dynamic Gaussian Splatting has driven significant advances in free-viewpoint video, maintaining its rendering quality with a small memory footprint for efficient streaming tr…
