Image Compression and Deblurring



Anastase Nakassis, Alfred S. Carasso


What follows is the description of an experiment in which we investigated the possibility that blurring techniques and lossless compression could be combined as an alternative to lossy compression techniques for still images. Our results show that while blurred images compress losslessly better than their originals, this technique offers relatively modest compression ratios which can be matched by lossily compressed images (JPEG) having less noticeable artifacts.
