A method of restoring a digital image, the method comprising partitioning the image into a plurality of blocks of pixels, processing each block to produce a restored block and concatenating the restored blocks to produce a restored digital image, wherein the step of processing each biock comprises: i) padding the block with additional pixels having values extrapolated from a range of pixel values across the block to produce a padded biock; si) performing a Fourier transform operation on the padded block to produce a transformed block; iii) applying an inverse biur filler to the transformed padded block to produce a filtered block; and Iv) performing an inverse Fourier transform on the filtered block to obtain the restored block. |
