A hybrid differential encoder and non-linear filter (DEN filter)

A system is presented to combine two goals in image processing; compression and non-linear filtering. The compression is done using a modified differential Huffman coding technique. The non-linear filter uses a bounding technique to filter impulse noise while passing edges. Simulation results are presented in tabular form, along with several original and filtered images added for subjective viewing. Future avenues of research, possibly leading to higher compression ratios, are suggested.<
