Claim:
1. A method for converting between aspect ratios, comprising: obtaining an input image having a source aspect ratio; applying, by a processing device, a transformation to the input image to scale and warp the input image to generate an output image having a target aspect ratio, the target aspect ratio different than the source aspect ratio, the output image non-linearly warped relative to the input image such that a distortion in the output image relative to the input image is greater in a corner region of the output image than a center region of the output image, wherein applying the transformation comprises shifting pixels of the input image by an amount represented by a non-linear function of original pixel positions of the pixels, wherein applying the transformation to the input image to scale and warp the input image comprises: outputting the output image having the target aspect ratio.
