11. The method of claim 10 , further comprising: computing the plurality of first image pixel set features such that each first image pixel set may be computed as a linear combination of the subset of the plurality of first image pixel set features with first weights for each feature in the subset; computing the corresponding plurality of second image pixel set features such that each second image pixel set may be computed as a linear combination of the subset of the corresponding plurality of second image pixel set features with the same first weights for each feature in the subset as the corresponding first weights for each feature in the corresponding subset; for each of the first particular image sets: identifying, with the particular subset of the plurality of first image pixel set features, second weights for each feature such that the first particular image pixel set may be computed as a linear combination of the particular subset of the plurality of first image pixel set features with the second weights for each feature in the particular subset; computing the second particular image pixel set as a linear combination of the identified corresponding second image pixel set features with the same second weights for each feature in the subset as the corresponding second weights for each feature in the corresponding particular subset.
10. A method comprising: receiving a first plurality of images at a first image resolution and a second plurality of images at a second image resolution, wherein the first image resolution is lower than the second image resolution; for each image of the first plurality of images: transforming the image into a transformed image of the second image resolution; identifying a plurality of first image pixel sets comprising a plurality of pixels of the transformed image; identifying, for each first image pixel set, a corresponding second image pixel set of the second plurality of images; storing each first image pixel set and each corresponding second image pixel set in a database repository of corresponding image pixel sets; based on the first image pixel sets in the database repository of corresponding image pixel sets, computing a plurality of first image pixel set features, wherein each first image pixel set may be computed as a linear combination of a subset of the plurality of first image pixel set features; based on the first image pixel set features for each first image pixel set and corresponding second image pixel set, computing a corresponding plurality of second image pixel set features, wherein each first image pixel feature corresponds to a second image pixel set feature of the corresponding plurality of second image pixel set features, and wherein each second image pixel set may be computed as a linear combination of a subset of the corresponding plurality of second image pixel set features and each second image pixel feature of the subset corresponds to a first image pixel feature in the subset of the plurality of first image pixel set features for the first image pixel set that corresponds to the second image pixel set; storing, in a data record, each first image pixel feature and each corresponding second image pixel feature; receiving a first particular image at the first image resolution; transforming the first particular image from the first image resolution to the second image resolution; identifying a plurality of first particular image pixel sets of the transformed particular image; for each of the plurality of first particular image pixel sets: identifying a particular subset of the plurality of first image pixel set features such that the first particular image pixel set may be computed as a linear combination of the particular subset of the plurality of first image pixel set features; for each first image pixel set feature of the particular subset, identifying a corresponding second image pixel set feature; computing a second particular image pixel set as a linear combination of the identified corresponding second image pixel set features; generating and displaying, on a computing device, a second particular image from the second particular image sets.
