Rebuild Fingerprints

The digiKam Maintenance Options to Rebuild the Fingerprints

Fingerprints are necessary for finding duplicates and similar items and for finding images by sketches. For a detailed description see the Similarity View section of this manual.

The Rebuild Fingerprints tool provides only one option to rebuild the contents in the database: Scan for Changed or Non-Cataloged Items. This option speeds the rebuild process by ignoring unchanged items that are already in the database.

备注

This process can also be called from the Similarity View in the left sidebar by clicking the Update Fingerprints button.
