Fingerprint images data base

Here you are a data base of image samples grabbed with the UniBO fingerprint capacitive sensor. Each file is a TIFF image. Each file name is coded as follows:


Each TIFF image contains a collection of 10 images taken in real time with changed cell "sensitivity". This process can be helpful for algorithmic manipulation. If you want to download the entire database, you can use the UNIX tar file DB_TIFF.tar

At the time of acquisition the sensor was not at its best. Please, take images AS IS.
