Vipkurum question cropping — the page's geometry sets the edge, not a hand
The question cropping tool we wrote under the Vipkurum roof. As a booklet page is separated into single questions, the place of each cut is set by the geometry of the page rather than by a hand: Python and OpenCV read the edges out of the image. Upload the same page again and it divides along the same lines, so the margin does not move with whoever picked the job up. Cropped images and question records sit in MongoDB, and the image processing service reaches the Laravel content side through Node.js. The scope is education material; a booking diary, a patient file or a treatment plan are not work we can show.
