How do you make image occlusion cards?
To make image occlusion cards, take a labeled diagram, draw a box over each label, and turn each box into a card that hides one part. You study by looking at the masked diagram and recalling what is underneath. You can draw the boxes by hand in Anki, or upload the diagram to a tool that masks every label for you automatically.
The slow way is manual. In Anki's built-in Image Occlusion you paste one image and drag a rectangle over every label, which can mean dozens of boxes per diagram. It works, but it is the part most students dread, and it has to be redone for every new picture.
The fast way is automatic. You give a tool the diagram, or your whole lecture, and it detects the printed labels and masks them for you. You start from a finished deck and only nudge a box if it sits slightly off.
- 1Choose a diagram with clear printed labels.
- 2Decide what to hide: every label, or only the high-yield ones.
- 3Mask each label with a box, by hand or automatically.
- 4Make one card per diagram, or one card per label if you want them separated.
- 5Study the masked version, reveal to check, and rate how it went.
- 6Export to Anki so spaced repetition brings the hard ones back.
