Image occlusion cards hide specific parts of an image so you can recall what is underneath. Each hidden region becomes a prompt. When you reveal it, you check if the recalled label, value, or feature was correct. This trains precise visual memory and location-based recall.

🎯 When to use

• Anatomy labels on diagrams or histology slides

• Maps, flags, and geography labels

• Circuit symbols and engineering schematics

• Chemical structures and pathways

• Process diagrams and flowcharts

• Tables where single cells must be remembered

📚 How to study them

• Look at the image with one region hidden and try to recall exactly what sits under the mask.

• Reveal the answer and grade yourself honestly.

• If recall is fuzzy, make the mask smaller or split it into multiple focused cards.

• Mix occlusion cards with regular Q&A cards to reinforce context and definitions.

✅ Good practices

• Keep each card atomic: one hidden fact per mask.

• Prefer readable fonts and clean images with minimal clutter.

• Avoid overlapping masks.

• Place masks consistently so your eyes learn stable landmarks.

• Use short, unambiguous answers.

• Periodically prune or merge cards that feel redundant.

⚠️ Common pitfalls

• Masks that cover too much lead to vague prompts.

• Low-quality images force guesswork.

• Cramming many labels into one card reduces retention.

• Ignoring context. Pair occlusions with concise text cards for definitions and why it matters.

In short, image occlusion turns any labeled diagram into targeted, location-aware practice that makes visual knowledge stick.
