New AI framework LucidNFT enhances image super-resolution with reinforcement learning

Researchers have developed LucidNFT, a new framework for real-world image super-resolution that uses reinforcement learning to improve image quality while maintaining faithfulness to the original low-resolution input. The system addresses issues like semantic hallucinations and loss of reward contrast by introducing LucidConsistency, a degradation-invariant evaluator, and a decoupled reward normalization strategy. Experiments and human studies indicate that LucidNFT enhances perceptual quality and faithfulness compared to existing methods, with outputs being judged more faithful in a significant majority of comparisons.
