Contour Smoothing [message #1988] Fri, 15 April 1994 07:15

I've been doing a lot of contour overlays of one image onto another where
the images are a different wavebands, say radio over x-ray. Frequently
the data has large differences in the pixel sizes. Doing the coordinate
transformation and regridding the image is no problem. However, in order
to preserve resolution I tend to "blow-up" the smaller pixels to match the
larger pixel size. Then when I do a contour it tends to a ragged, "blocky"
appearence. I'd like to get a smoother contour, possible some sort of
spline interpolation. The problem is that I can't use the min_curve_surf
routine because my images are too large. I run out of virtual memory,
even with over 200 Mb allocated. Any suggestions?
