Abstract
A method and apparatus for image interpolation provides a simple method that can up-scale an image in various scale ratios, including fractional scaling ratios, and can yield a sharp image with reduced unpleasant visual artifacts. An embodiment uses a power weight function that is gradient dependent and uses a function that has a linear dependence on the distance to compute interpolated pixels. A further embodiment uses a power that can be adapted according to the local contrast of edges.
