    摘要: A method to generate super-resolution images using a sequence of low resolution images is disclosed. The method includes generating an estimated high resolution image, motion estimating between the estimated high resolution image and comparison images from the sequence of low resolution images, motion-compensated back projecting, and motion-free back projecting that results in a super resolved image. A corresponding system for generating super-resolution images includes a high resolution image estimation module, a motion estimating module, a motion-compensated back projection module, a motion-free back projection module, an input interface, and an output interface.

    摘要: Presented herein are caching structures and apparatus for use in block based video. In one embodiment, there is described a system receiving lower resolution frames and generating higher resolution frames. The system comprises an upsampling circuit, a first circuit, and a second circuit. The upsampling circuit upsamples a particular lower resolution frame, thereby resulting in an upsampled frame. The first circuit maps frames that are proximate to the particular frame, to the particular frame. The second circuit simultaneously updates the upsampled frame with two or more blocks from at least one of the frames that are proximate to the particular frame.
