Bit Allocation Transfer for Perceptual Quality Enhancement of Traditional Video Codecs
Runyu Yang, Ivan V. Bajić
Traditional block-based video codecs, such as H.264/AVC, H.265/HEVC and H.266/VVC, rely on hand-crafted Rate-Distortion Optimization (RDO) processes that primarily minimize Mean Sq…
Context Adaptive Extended Chain Coding for Semantic Map Compression
Runyu Yang, Junqi Liao, Hyomin Choi +2
The paper proposes a lossless compression method for semantic maps that uses an extended chain coding scheme with context‑adaptive entropy coding and a skip‑coding mechanism to red…
ChWDTA: Channel-wise Wavelet-Domain Transformer Attention and Entropy Modeling for Learned Image Compression
Haisheng Fu, Runyu Yang, Feng Ding +5
State-of-the-art learned image compression (LIC) schemes are increasingly based on hybrid CNN-transformer architectures. To further improve rate-distortion performance, we introduc…
Bit Allocation Transfer for Perceptual Quality Enhancement of VVC Intra Coding
Runyu Yang, Ivan V. BajiÄ
Mainstream image and video coding standards -- including state-of-the-art codecs like H.266/VVC, AVS3, and AV1 -- adopt a block-based hybrid coding framework. While this framework…
