METHOD AND SYSTEM FOR IMAGE SCALING

摘要

A method, system, and non-transitory computer-readable storage medium for image scaling is provided. In one embodiment, the method may include determining one or more filter phases based on a vertical target grid distance and a horizontal target grid distance; and scaling, by one or more hardware processors, an input image using filter coefficients corresponding to the one or more filters phases to output a target image. The horizontal target grid distance may be based on a ratio of a number of horizontal filter phases and a horizontal scaling ratio, and the vertical target grid distance may be based on a ratio of a number of vertical filter phases and a vertical scaling ratio.
