Perceptual Quality Optimization of Image Super-Resolution
Wei Zhou, Yixiao Li, Hadi Amirpour +4
Single-image super-resolution (SR) has achieved remarkable progress with deep learning, yet most approaches rely on distortion-oriented losses or heuristic perceptual priors, which…
Is there a relationship between Mean Opinion Score (MOS) and Just Noticeable Difference (JND)?
Jingwen Zhu, Hadi Amirpour, Wei Zhou +1
Evaluating perceived video quality is essential for ensuring high Quality of Experience (QoE) in modern streaming applications. While existing subjective datasets and Video Quality…
Cross-Modal Scene Semantic Alignment for Image Complexity Assessment
Yuqing Luo, Yixiao Li, Jiang Liu +7
Image complexity assessment (ICA) is a challenging task in perceptual evaluation due to the subjective nature of human perception and the inherent semantic diversity in real-world…
