ColorFilterTest now creates colorcode statistics.
ColorFilterTest: refactor, moved TransitionStat and its internals into libImageFilter.
ColorFilterTest can now make statistics using two list of filenames.
Added JPEG to gitignore.
ColorFilterTest += search for promising values sequences and using auxScore.
+= MarkovFsmTest
ColorFilterTest -= functions moved to MarkovFsmTest
MarkovFsmTest += runlength quantizing
MarkovFsmTest -= higher functions moved to libImageFilter.TransitionStat
MarkovFsmTest += FSM state-merge functions
ImageProcessing.TransitionStat and FsmLearner separated.
MarkovFsmTest: FsmLearner's additional functions moved into the class
Tidy-up of MarkovFsmTest/fsmlearning.cpp, update ImageProcessing.
MarkovFsmTest += uses precision based status and tree cut functions
MarkovFsmTest: test_mkStatFromImageList moved to fsmlearning.cpp
MarkovFsmTest += dagnode (initial commit, unfinished)
MarkovFsmTest DAG handling extended... in progress...
MarkovFsmTest: Using improved runlength encoding with higher markov chain order.
