interpolate over bad pixels [message #44560]

I was hoping you could help me out here. I have a set of images where a
few pixels are bad, or set to "NaN". Can you tell me how I can
interpolate over these bad pixels, using preferrably a spline or cubic
interpolation? The region with bad pixels is usually around 3-8 pixels
in diameter on a 1024x1024 image. Is there a routine that takes the
image and a list of the indices of bad pixels, and outputs an
interpolated image?

I have looked at the convol routine, and tri_surf. If these do what I
need them to do, I have not figured out how to use them...

Thanks,
Em
