Abstract

Techniques are disclosed for rendering images. The techniques include receiving an input image associated with a source space, the input image comprising a plurality of source pixels, and applying an adaptive transformation to a source pixel, where the adaptive transformation maps the source pixel to a target space associated with an output image comprising a plurality of target pixels. The techniques further include determining a target pixel affected by the source pixel based on the adaptive transformation. The techniques further include writing the transformed source pixel into a location in the output image associated with the target pixel.

First claim

What is claimed is:

1. A computer-implemented method to non-linearly warp an input image from a source aspect ratio to a target aspect ratio, the computer-implemented method comprising:
receiving an input image associated with a source space having the source aspect ratio, the input image comprising a plurality of source pixels;
applying an adaptive transformation to a source pixel within the plurality of source pixels and by operation of one or more computer processors, the ad…
