US Patent 12118692 Image super-resolution

Techniques are described for upscaling low-resolution image data. In an embodiment, input image data of a low-resolution image is received to generate output image data for a high-resolution image of the low-resolution image. The input image data is interpolated to match the output size, and, based on the original input image data, the residual image data is determined. The interpolated image data is combined with the residual image data to generate the output image data for the high-resolution image of the output size. The techniques further include training one or more learning models for determining the residual image data based on the original input image data.
