[Vxl-users] extending Harris detector

[Nick H. <nic...@ya...>]

Hi, I'm looking for some advice on extending the osl_harris corner detector in
the oxl library to a multi-scale detector.  I've been playing around with it a
little, but wanted to see if anyone who has worked with the code might have an
opinion on the "right" way to do it.

I was going to make a subclass harris_scaled, but the original doesn't appear
to be set up for subclassing and I don't want to modify library code.  I was
experimenting with iteratively applying a Gaussian and running the basic
detector after each smoothing run, but I must be using osl_create_gaussian or
osl_convolve inappropriately because after smoothing the image is very noisy --
all-black regions that should stay black are not and other regions appear
noisy, not smoothed.

I'll keep playing with it and probably figure it out, but if any veterans have
any helpful tips, they'd be appreciated.

thank you,
Nick Hurlburt
