An industrial assembly line with several stations along it. Stations from left to right (from station 1 (left) next to station 2 (left middle) next to station 3 (middle) next to station 4 (middle right) next to station 5 (right)). Station 1 (Start): An image of a handwritten test question (in ink, with crossed-out words and margin notes). Station 2: From Station 1, the assembly line leads to a machine called “Preprocessing” (image preprocessing). You can see gears processing the image. After passing through the machine, there should be two images on the assembly line—one with gears and the other without. Station 3: After Station 2, the assembly line splits into two: Assembly Line A: Runs past this station directly to Station 4. Assembly Line B: Runs into an “image-to-text” machine. Station 4: VLM Evaluation Machine: Port 1: From Assembly Line A: The direct image is evaluated. Port 2: From Assembly Line B: OCR text is evaluated. Port 3: Manually digitized text (An arrow leads from Station 1 to a person who digitizes the text, and then the arrow continues to Station 4, Port 3). After Station 4, the conveyor belt proceeds to Station 5; the maximum and awarded scores for the assignment are displayed on the conveyor belt. Station 5 (End): The conveyor belt reaches its end, and the maximum and awarded scores for the assignment are displayed. Next to Station 5, a human teacher (with a pen and glasses) can be seen grading tests. Between Station 5 and the teacher is the abbreviation Ver más
