hi,
i think this is a fairly easy problem to which i dunno the answer.
Here goes:

I have 3 images, and used where function 3 times to find 3 specific
characterizations.
mask1=where(image ge thresh1)
mask2=where(image2 ge thresh2)
mask 3=where(image3 ge thresh3)

Now I have 3 sets of indices of pixels of my interest.

I want to use image 4 and color pixels indices 1 red, indices 2= blue,
indices 3=green.

image[indices1]=red
image[indices2]=blue
image[indices3]=green

How do I do that?

Thanks
rp
