Hey, all. I've been using scipy.ndimage.morphology.binary_opening on images around 15000 x 5000 in size (scans of old seismograms!). I did a quick comparison with open cv's cv2.morphologyEx and noticed the cv2 opening was about 10x faster. Is this expected? I don't know much about how scipy and opencv differ under the hood. If unexpected, I'll take a closer look at the two. (I was kindly pointed to this google group by folks replying to my github issue: https://github.com/scipy/scipy/issues/5333.) --Benny
