Thanks to the collaboration with the INRIA, a first version of the aspired application is already available, through a website which allows to take and upload photos of watermarks.
It is possible to access and use it on a computer or a mobile phone at the address: https://filigranes.inria.fr.
For more information about the optical recognition technology developed for the project see the article “Large-Scale Historical Watermark Recognition:dataset and a new consistency-based approach“.
