How does anime upscaler work
Anime image upscaling is performed by an AI model that reconstructs higher resolution versions of illustrated images using learned patterns from anime artwork. The system evaluates how lines, shapes, and color areas are arranged in the original image, then estimates additional pixel information required to scale the image up.
A GAN-based architecture trained on large collections of anime-style images is used to infer missing details during enlargement. Instead of enlarging existing pixels, the model synthesizes new ones that follow the visual logic of drawn content, maintaining consistent outlines and color separation as resolution increases.
