CONT

Generally speaking, image quality evaluation has something to do with the purpose of the image. Image quality has two implications: fidelity and intelligibility. The former describes how the reconstructed image differs from the original one, with mean-square-error as a typical example, and the latter shows the ability through which the image can offer information to people, with classification-accuracy as a typical example. Both are foundamental in measuring the image quality.
