Abstract
A super-resolution image is generated from a pixel image by first performing an initial image interpolation, creating an interpolated low resolution image. The interpolated low resolution image is then partitioned into overlapping low resolution patches. The low resolution patches are then processed in a raster scan order. For each low-resolution patch, a scaled mid band patch is generated. A search vector is constructed from pixels in the scaled mid band input patch, and pixels in an overlap region of adjacent previously predicted high band patches. A nearest index vector to the search vector is located in a training database, the nearest index vector has an associated high band output patch. The high band output patch is then combined with the interpolated low resolution patch to predict pixel values for the corresponding high resolution patch of the super-resolution image.
