New SDGIC method improves semantic consistency in generative image compression

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new generative image compression method called SDGIC, designed to maintain semantic consistency at ultra-low bitrates. This framework addresses the issue of semantic ambiguity in generative compression by using three distinct guidance streams: a text caption for global semantics, a highly compressed image for visual details, and Reconstruction-Aware Semantic Residual Tokens (RSRTs) for reconstruction-specific semantic constraints. These streams are integrated into a Dual-Path Conditioned Diffusion Decoder to effectively guide the diffusion-based reconstruction process. Experiments show SDGIC significantly improves semantic consistency while preserving perceptual quality, achieving a 23.4% reduction in AFINE on the CLIC2020 dataset. AI

IMPACT This method could enable more reliable deployment of generative image compression in bandwidth-constrained environments like 6G semantic communications.

    SDGIC: A Semantic Disambiguation-Guided Generative Image Compression Method for Ultra-Low Bitrates

    arXiv:2512.06344v2 Announce Type: replace Abstract: Generative image compression has recently shown impressive perceptual quality, but often suffers from semantic inconsistency at ultra-low bitrates (bpp < 0.05), limiting its reliable deployment in bandwidth-constrained scenarios…
