Abstract
Systems and methods are disclosed for coding images. For example, methods may include: receiving an encoded bitstream that was generated at least in part by applying a sharpening filter to an input image to obtain a sharpened image and applying a blockwise encoder to the sharpened image; decoding, using a blockwise decoder, data from an encoded bitstream to obtain a plurality of blocks of image data; combining the plurality of blocks of image data to form a blocked image; and applying a blurring filter, which is matched to the sharpening filter, to the blocked image to obtain an output image.
