Fast and edge-preserving upsampling of images

Abstract:

Disclosed herein are methods and systems for fast and edge preserving upsampling of a small data image based on one or more guide images. During the upsampling process, selected data from the one or more guide images are combined with data from the data image to generate an upsampled pixel in an upsampled image. The upsampling can occur directly from the data image or sequentially via one or more intermediate upsampled images.
