Towards True Detail Restoration for Super-Resolution: A Benchmark and a Quality Metric

Understand

Super-resolution (SR) has become a widely researched topic in recent years.

• SR methods can improve overall image and video quality and create new possibilities for further content analysis.
• But the SR mainstream focuses primarily on increasing the naturalness of the resulting image despite potentially losing context accuracy.
• Such methods may produce an incorrect digit, character, face, or other structural object even though they otherwise yield good visual quality.
