LOSSLESS IMAGE CODING ALGORITHM FOR SAR BASED ON REVERSIBLE LIFT SCHEMATICS COMBINED WITH CONTEXT PREDICTOR
Rong Liu · Acta Aeronautica Et Astronautica Sinica · 2002
A lossless image coding algorithm for SAR was proposed, which adopts the reversible lift schematics combined with the context predictor. The reversible lift schematics can efficiently reduce redundant in the SAR image and the context predictor has excellent adaptive edge prediction and smooth prediction abilities. The adaptive context modeling mostly improves the entropy coding ratio. The algorithm has a higher compression ratio than the lossless part in the incoming ISO standard JPEG2000, besides the normal virtue of wavelet coding.
