Re: integral image for each depth in a three dimensional array

6 Aug 2013


      Hi,

That's the way to do it, but I'd directly save the result in the output array:
...
ret = np.empty_like(image)
for i in range(depth):
      ret[:,:,i] = integral_image(image[:,:,i])

Hi all,
I want to calculate integral images for each depth in a three dimensional array.
My code is something like this:
ret = np.empty(height, width, depth)
int_imgs = [integral_image(image[:,:,i]) for i in range(depth)]
for i in range(depth):
      ret[:,:,i] = int_imgs[i]
Is there better way to do this?
Thanks,
masa
