One-pass super-resolution images

A method for generating a super-resolution image from a pixel image, comprising:

• partitioning the pixel image into a plurality of overlapping low resolution patches;
• partitioning the super-resolution image into a plurality of corresponding overlapping high resolution patches;
• processing the low resolution patches in a sequential order, the processing for each low-resolution patch comprising:
• generating a scaled mid band patch from the low resolution patch;
• constructing a search vector from pixels in the scaled mid band input patch, and pixels in an overlap region of adjacent previously predicted high band patches;
• locating a nearest index vector to the search vector in a training database, the nearest index vector having an associated high band output patch;
• and
• combining the high band output patch with the interpolated low resolution patch to predict pixel values for the corresponding high resolution patch of the super-resolution image.
