What is AI Image Upscaling?
TL;DR: AI image upscaling (super-resolution) increases image resolution while adding realistic detail that doesn't exist in the original. Unlike simple resizing which creates blurry results, AI upscaling generates new pixels based on learned patterns.
Neural networks trained on millions of high-resolution images learn the relationship between low and high-resolution versions. When given a small image, the AI predicts and generates the missing detail — sharpening text, adding texture detail, and producing clean edges.
