Patent ID: 8514932

Claim:
A computer-implemented method to encode images, the method comprising: receiving a retargeted sequence of images having a target image resolution, wherein the retargeted sequence of images is retargeted from a source sequence of images having a source image resolution, the source image resolution having a different aspect ratio than the target image resolution; determining at least one non-linear warp function configured to generate a predicted sequence of images having the source image resolution from the retargeted sequence of images having the target image resolution; determining differences between the predicted sequence of images having the source image resolution and the source sequence of images having the source image resolution by operation of one or more computer processors; and generating a bitstream by encoding at least three components including: (i) a first component comprising the received retargeted sequence of images having the target image resolution; (ii) a second component comprising the at least one non-linear warp function; and (iii) a third component comprising the determined differences; wherein the bitstream is decodable to generate a sequence of images in the target image resolution based on the first component and also decodable to generate a sequence of images in the source image resolution based on the three components.
