Vipkurum question cropping — OpenCV splits the page, the key enters the record
The cropping and key matching tool we wrote under the Vipkurum platform. A booklet page is separated into individual questions by image processing: OpenCV works out the boundaries, never a language model. Gemini and OpenAI models attach the answer from the key to the question it belongs to, so the key stops being a separate document and enters that question's record. A question nobody has can be written from existing examples, with its answer. Cropped images and records sit in MongoDB, reached through Node.js from the content management side on Laravel. Cropping stays in image processing, interpretation in the model.
