8.3: Visual Modeling of Upscaled Image Discrimination

Abstract This paper describes the application of a visual model to the spatial upsampling problem. The visual model includes an updated optical pointspread function that is adapted to a particular display's spectral emission characteristics. The visual model identifies locations of visible differences between high resolution groundtruth and 2X upsampled images, and allows quantifying the degree of difference between competing algorithms. Subjectivelydetermined image difference thresholds are compared to model predictions for both upsampsled Bluray and highresolution still images.
