I'm trying to understand the CR metric. Does it represent the percentage of all enhanced images that are considered high-quality (compared to both high-quality and usable results)?
Question 2:
The other metrics mentioned (Accuracy, Kappa, AUC) seem to relate to a model trained for classifying images as high-quality, usable, or rejected only and there is no relation in enhancement here am I missed something?
I want to ask about rows for example the row "ours" this calculated between the degraded images and their corresponding enhancement images or (between the original high quality images and their enhancement)
