METHOD AND APPARATUS FOR GENERATING OF SUPER RESOLUTION IMAGE

摘要

Disclosed is a method for generating an image using a super resolution technique, which comprises the following steps: decomposing an input image into a low frequency image and a high frequency image by using a filter; generating an enlarged image of the low frequency component by interpolating the input image; searching a similar patch which has the highest similarity from the low frequency image by using the enlarged image as a patch unit; copying and mapping a patch in the high frequency image corresponding to the searched similar patch into a high frequency image of a higher layer which has a higher resolution than the high frequency image; and merging the enlarged image and the high frequency image of the higher layer to generate a high resolution image which has a higher resolution than the input image.
