BRIGHTNESS-COMPENSATING SAFE PIXEL ART UPSCALER |
摘要 |
Low spatial frequencies of an original image and an upscaled filtered image are analyzed. Differences will be observed in the low frequency components of the two images in the general case since the pixel art upscaler filter as a side effect introduces low frequency changes. A modification to images produced by the PAU is applied to attempt to match the brightness of the original images in the low frequency spectrum. From a viewer perspective (e.g., based on typical blurring visual effects), the original image and the modified filtered image will look the same –demonstrating that there is no low frequency brightness creep or resulting increased photosensitivity concerns. |
