ABSTRACT:
Methods, data, and systems are provided to warp an image. Input pixels associated with an input image are warped according to a provided or obtained warping function. A single weight is assigned to each input pixel. The weight represents each input pixel's horizontal and vertical dimensions within an output lattice. The single weight is combined with an intensity value associated with each input pixel to map each input pixel to the output lattice in a single processing pass.
