I can resize a 2d image "im" with a command something like: r,c = shape(im) im2 = resize(im,(r//2,c//2))
However, resize doesn't seem to work with an RGB image: r,c,n = shape(im) # returns, say 500 600 3 I then need to take each band separately, resize it, and put them all back together with dstack: imr = im[:,:,0] img = im[:,:,1] imb = im[:,:,2] imr2 = resize(imr,(r//2,c//2)) img2 = resize(img,(r//2,c//2)) imb2 = resize(imb,(r//2,c//2)) im2 = dstack((imr2,img2,imb2)) This works fine, but seems a little clumsy. Of course this could be done in one command: im2 = dstack([resize(im[:,:,i],(r//2,c//2)) for i in range(3)]) What I want to know is: is there a version of resize which can be applied directly to multi-band images, without having to apply to each band separately?
