Abstract
Official abstract text for this publication.
Provided are an apparatus and method of obtaining a high resolution image using multi-band combination filters. The apparatus includes a high frequency extraction unit to extract a high frequency image from a low resolution input image through filtering operations performed in parallel, a high frequency expansion unit to expand the high frequency image to generate an expanded high frequency image, an image expansion unit to expand the low resolution input image to generate an expanded input image, and an image combination unit to combine the expanded high frequency image and the expanded input image.
First claim
Opening claim text (preview).
What is claimed is: 1. An apparatus for obtaining a high resolution image, the apparatus comprising: a processor comprising: a high frequency extraction unit to extract a high frequency image from a low resolution input image through filtering operations performed in parallel wherein the high frequency extraction unit comprises a plurality of filters to filter the low resolution input image using a predetermined plurality of frequency bands, which are different bands from each o…
