RAWIC: Bit-Depth Adaptive Lossless Raw Image Compression
Chunhang Zheng, Tongda Xu, Mingli Xie +2
Raw images preserve linear sensor measurements and high bit-depth information crucial for advanced vision tasks and photography applications, yet their storage remains challenging…
Successive Cancellation Decoding For General Monotone Chain Polar Codes
Zichang Ren, Chunhang Zheng, Dou Li +1
Monotone chain polar codes generalize classical polar codes to multivariate settings, offering a flexible approach for achieving the entire admissible rate region in the distribute…
SEEC: Segmentation-Assisted Multi-Entropy Models for Learned Lossless Image Compression
Chunhang Zheng, Zichang Ren, Dou Li
Recently, learned image compression has attracted considerable attention due to its superior performance over traditional methods. However, most existing approaches employ a single…
GeNet: A Graph Neural Network-based Anti-noise Task-Oriented Semantic Communication Paradigm
Chunhang Zheng, Kechao Cai
Traditional approaches to semantic communication tasks rely on the knowledge of the signal-to-noise ratio (SNR) to mitigate channel noise. Moreover, these methods necessitate train…
