Seven Challenges in Image Quality Assessment: Past, Present, and Future Research
Figure 9
Demonstration of the visual effects of disrupting the HVS's ability to integrate features across scale space. The original image is shown on (a), and the distorted version is shown on (b). The distorted image was generated by notch-filtering discrete-space radial frequencies of to . This filtering disrupts the HVS's ability to integrate information at different scales, and thus the high-frequency content is perceived as additive noise on top of a blurry image in the background.
