Histograms of TE values. a The six curves correspond to an undistorted image and its distorted counterparts with the same distortion level but different distortion types. The DMOS values are around 25. b The six curves correspond to an undistorted image and its distorted counterparts with the same distortion level but different distortion types. The DMOS values are around 50. c The six curves correspond to an undistorted image and its distorted counterparts with the same distortion type but different distortion levels. The distortion type is WN. d The six curves correspond to an undistorted image and its distorted counterparts with the same distortion type but different distortion levels. The distortion type is GBlur
