GRACE: Designing Generative Face Video Codec via Agile Hardware-Centric Workflow
Rui Wan, Qi Zheng, Ruoyu Zhang +6
The Animation-based Generative Codec (AGC) is an emerging paradigm for talking-face video compression. However, deploying its intricate decoder on resource and power-constrained ed…
M3-CVC: Controllable Video Compression with Multimodal Generative Models
Rui Wan, Qi Zheng, Yibo Fan
Traditional and neural video codecs commonly encounter limitations in controllability and generality under ultra-low-bitrate coding scenarios. To overcome these challenges, we prop…
Unicorn: Unified Neural Image Compression with One Number Reconstruction
Qi Zheng, Haozhi Wang, Zihao Liu +8
Prevalent lossy image compression schemes can be divided into: 1) explicit image compression (EIC), including traditional standards and neural end-to-end algorithms; 2) implicit im…
LiteVAR: Compressing Visual Autoregressive Modelling with Efficient Attention and Quantization
Rui Xie, Tianchen Zhao, Zhihang Yuan +5
Visual Autoregressive (VAR) has emerged as a promising approach in image generation, offering competitive potential and performance comparable to diffusion-based models. However, c…
