Abstract
A method of generating a super-resolution image from a single frame includes receiving, at a processor, first image data having a first resolution as a query image layer, acquiring, by the processor, second image data as a copy image layer, generating, by the processor, at least one additional image layer as a retrieval layer, the at least one additional image layer having a resolution lower than the first resolution, wherein the lower resolution corresponds to the first resolution divided by a scaling factor, generating high resolution image data for a high resolution layer having a resolution higher than the first resolution, the generating including copying image data from the copy layer when a match is found and upscaling the query layer when a match is not found.
