Tutorial for the web application

Connect to http://filigranes.inria.fr.

Use the application via your computer and/or download it on your smartphone.

To take the photograph of your watermark, stay in the frame which is automatically given: your watermark must not be out of the borders. After placing the watermark rightly, choose “Photo”.

To upload the image of a watermark you already have on your smartphone or computer, choose “Fichier” (file).

Once your picture uploaded, choose “Chercher les correspondances” (look for the matchings).

The list of the proposed matchings is shown under the uploaded picture.

Every matching is linked to a basic descriptive record of the candidate watermark.

If your search does not give any result, you can choose to become a contributor and add your watermark, creating your own descriptive record.
