1. An apparatus to perform edge aware upscaling, the apparatus comprising:
memory;
instructions; and
processor circuitry to execute the instructions to:
determine whether potential edge pixels of an input image include a thin edge;
determine whether the potential edge pixels of the input image include a one-directional edge; and
derive a target output pixel value, the target output pixel value based on an edge type and a classification of a corresponding input pixel of the potential edge pixels, the edge type is at least one of the thin edge or the one-directional edge, the classification is a leading-edge pixel classification or a fading-edge pixel classification.
