Complete label coverage: the no-leakage review standard
A before-and-after review standard for checking that every image-occlusion mask covers the complete label without hiding the diagram target.
Occlusion result
Original source
Quality checks
Whole label covered
Every mask includes the full word or wrapped phrase, so no suffix remains visible as an answer hint.
Target remains visible
Masks cover label text, not the heart structure the learner must identify.
One answer per mask
Each mask corresponds to a single structure and produces one independently reviewable card.
Source comparison
The original figure remains available during deck review so the generated answer can be verified before export.
What to copy from this example
- →Reject masks that leave even part of the answer readable.
- →Do not cover the structure itself unless the learning goal is shape recall.
- →Verify the answer against the source figure before sending the deck to Anki.
