Re: Adaptive Huffman algorithm !!!


Try using Range coding instead. Force the output bits (a maximum of
2 each step). That should give you a huff and puff coder . adaptive
huffman was a name invented by vitter before the CACM codec was
unleashed on the users.

In theory huffman coder is a Arithmetic coder in which no bits are
left in the
the working region for the next symbol.
Search the net for range coder . That gentleman has posted a original
paper
by G.N.N. Martin on the subject.
