Summary

A new progressive learning approach for variable-rate deep image compression, published on 2026-06-15, integrates Low-Rank Adaptation (LoRA) to address the challenges of existing Deep Image Compression (DIC) techniques. This method introduces a LoRA Rate-Adaptive Module (LoRAM) into DIC frameworks, enabling a single model to achieve various compression rates without deploying multiple networks. Crucially, the re-parameterized merging of LoRA ensures no additional computational complexity during inference. Experimental results demonstrate that this approach delivers competitive performance while significantly reducing resource demands, specifically saving 99% in parameter storage, 90% in datasets, and 97% in training steps compared to multi-model alternatives. This advancement is critical for applications like web media, streaming, and medical imaging.
