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