Oh horrors. Please let it not be true that the phrase I am remembered most for is heuristic grass.
Your comments about MELP were insightful and now that you have said it, more becomes crystal clear. I raise another absinthe in your honor .... or was that dishonor.

If it is a detection problem, then you might as well just compress to the largest value in the bins to be pushed together so you assure that your threshold is exceeded when it should be. If it is a pretty picture problem, just prevent scalloping by any old heuristic, just make it as fleet of calculation feet as possible and throw in some pretty grassy stuff to make it look nice. > > Amen to that. > > To say so is not to dismiss the level of art required by heuristic grass, however. That's pretty much what MELP adds, and it makes a world of difference to the user. > > Frank >
