Q-SiT: Teaching LMMs for Image Quality Scoring and Interpreting

Understand

Image quality scoring and interpreting are two fundamental components of Image Quality Assessment (IQA).

• The former quantifies image quality, while the latter enables descriptive question answering about image quality.
• Traditionally, these two tasks have been addressed independently.
• However, image-quality-specific psychophysical studies suggest that these two tasks are conceptually interconnected: interpreting explicitly represents perceived quality attributes whereas scoring summarizes such evidence into an overall quality judgment.
