Adaptive coding

The Cassini camera was pointing toward DIONE at a distance of approximately 548,210 kilometers. The image was taken using the CL1 and CL2 filters on May 17, 2010.

Adaptive coding refers to variants of entropy encoding methods of lossless data compression. They are particularly suited to streaming data, as they adapt to localized changes in the characteristics of the data, and don't require a first pass over the data to calculate a probability model. The cost paid for these advantages is that the encoder and decoder must be more complex to keep their states synchronized, and more computational power is needed to keep adapting the encoder/decoder state.
