[Schrodinger-devel] dirac vs jpeg2k entropy modelling

[<jav...@uk...>]

 Hi,

   I want to do some experiments with dirac and j2k and I have a
   question. As I see dirac's entropy modelling is totally different from
   that of j2k. It would be interesting to know the rationale behind it.
   In particular if the j2k's entropy modelling (together with the
   dirac's arithmetic encoder which as I understans is more effective
   than j2k's quasi-arithmetic encoder) what size decrease can be
   expected?

   Thanks in advance,
   Vladimir
