Abstract
An apparatus for multi-stage super-resolution is described herein. The apparatus includes a personalized dictionary, a plurality of super-resolution stages, and a reference merger. Each of the plurality of super-resolution stages correspond to at least one personalized dictionary, and the personalized dictionary is applied to an input image that is sparse-coded to generate a reconstructed image. The reference merger is to merge the reconstructed image and the input image to generate a super-resolved image for each stage.

6. A method for multi-stage super-resolution, comprising:
-
generating a plurality of super-resolution stages, wherein each stage corresponds to a degradation operator and at least one personalized dictionary; reconstructing an input image at each super-resolution stage, wherein the at least one personalized dictionary is applied to a sparse code to form a reconstructed image; and applying reference merging to the reconstructed image and the input image to reduce error in the reconstructed image. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15)

16. A tangible, non-transitory, computer-readable medium comprising instructions that, when executed by a processor, direct the processor to:
-
generate a plurality of super-resolution stages, wherein each stage corresponds to a degradation operator and at least one personalized dictionary; reconstruct an input image at each super-resolution stage, wherein the at least one personalized dictionary is applied to a sparse code to form a reconstructed image; and apply reference merging to the reconstructed image and the input image to eliminate error in the reconstructed image. - View Dependent Claims (17, 19, 20)
