PerQ reframes image compression with inverse generative modeling

By PulseAugur Editorial · [1 sources] ·

Researchers have introduced PerQ, a novel approach to neural image compression that addresses the trade-off between pixel fidelity and perceptual quality. PerQ reframes perceptual reconstruction as inverse generative modeling, using a rate-conditioned flow-matching compensator attached to a pre-existing distortion-optimized backbone. This method allows for perceptual enhancement without sacrificing the backbone's coding performance. Experiments on standard datasets like Kodak and CLIC2020 demonstrate that PerQ achieves perceptual quality comparable to generative codecs while maintaining competitive PSNR, and a single model supports a wide bitrate range.

    PerQ: Inverse Generative Modeling for Neural Image Compression via Quantization Error Compensation

    arXiv:2610.27374v1 Announce Type: new Abstract: Neural image codecs face a fundamental trade-off between pixel fidelity and perceptual quality. Distortion-optimized codecs preserve pixel-wise fidelity but produce blurred reconstructions at low bitrates, whereas generative codecs …
