Hi! I am working on several compression techniques right now. I was at one time working on a form of MTF but abandoned it thinking it did worse than AdaptHuff. However, a few weeks ago, I resurrected it and found it was *better* than AdaptHuff. Following is the code I'm using to write MTF values:
----------------------
void mtfWriteVal (unsigned c)
{ unsigned m=mtfGetVal (c);
if (m<32) {
writeoutf_11 ();
writeoutf (m, 5);
} else if (m<64) {
writeoutf_x2 (2);
writeoutf (m-32, 5);
} else if (m<128) {
writeoutf (5, 3);
writeoutf (m-64, 6);
} else {
writeoutf (6, 3);
writeoutf (m-128, 7);
}
} ------------
where mtfGetVal() gives the value translated to MTF, writeoutf_01() and writeoutf_11() write one bit, writeoutf_x2() writes two bits and writeoutf() writes the number of bits given in the second argument.

This is an apples to oranges comparison. MTF could be included before
AdaptHuff, they aren't competing with each other.
