	I'm looking for a reference to a "Douglas-Peuker" filter. A
software implementation would also be nice, but for now, I'd be happy
with a reference to a paper I could read. If your fingers are itchy,
I'd be happy with a soft-copy.
	
	From what I can tell (from the context in which its
mentioned), it appears to be a filter for decimating datasets by
estimating the local slope of vector (array) and only saving points
when the slope changes significantly.

	Since I don't have much of a clue about this thing, I'd
suggest replying by e-mail unless you think its of general interest.

Thanks in advance,
-Dale
