This repository contains our series of works on Deep Hierarchical Video Compression.

• DHVC 1.0: The first hierarchical predictive coding method moves away from the hybrid coding framework, achieving best-in-class performance. Paper is available at Deep Hierarchical Video Compression (AAAI 2024).
• DHVC 2.0: The enhanced hierarchical predictive coding method, which integrates variable-rate intra- and inter-coding into a single model, delivering not only superior compression performance to representative methods but also real-time processing with a significantly smaller memory footprint on standard GPUs. Paper is available at High-Efficiency Neural Video Compression via Hierarchical Predictive Learning (arxiv 2024).
• DHIC: A spectrally regularized hierarchical image coding method, delivering not only superior compression performance but also efficient optimization without increasing inference complexity. Paper is available at Taming Hierarchical Image Coding Optimization: A Spectral Regularization Perspective (ICLR 2026).

[2026.1.26] Excited to share that our work on intra-frame hierarchical coding (DHIC) has been accepted by ICLR! The code will be open-sourced soon. 🚀

[2025.2.12] We have reconstructed the code and uploaded the pretrained models of DHVC 1.0.
