Description of the Library: Windsurf is a Java library having the goal of providing a general framework for the efficient processing of content-based image retrieval queries. In particular, the library primarily focuses on region-based retrieval and has the ability to encompass different querying models. Such flexibility is provided by a number of different facets, i.e., templates that can be appropriately instantiated in order to realize the particular retrieval model needed by the user.

The download of Windsurf Library implies that you have read and totally accepted all the terms of the following license and agree to become a licensee of the Windsurf Library.

The present license covers past, present and future releases of the Windsurf Library.

Access to future releases (if any) is automatically granted by this license and future releases shall be made available on the Windsurf website (

Terms of License

Statement of copyright and ownership

The Windsurf Library ("the Library") is the property of DEIS and bears DEIS copyright. Any use you make of the Library must respect DEIS proprietary rights.

Restrictions on commercial use of the Library

The Windsurf Library and all linking documentation is released under the Q Public License version 1.0 (or "QPL") listed in full text below integrated by the following specific provisions which form integral part of the license.

In addition to the terms imposed by the QPL, the Copyright's owner requires that all the rights granted by the QPL are granted for your own use only, for education and research purposes only, with the exclusion of any use or distribution for direct or indirect commercial purposes, included for monetary reward by means of sale, resale, loan, transfer, hire or other form of commercial exploitation.

On request, however, we are able to grant a differently licensed version of the Library that does not contain the restrictions said above. For this purpose, please, contact the Copyright's owners at the following e-mail address. You will be requested to grant a contribution to the Copyright's owners useful for continuing developing the library and funding further research on topics related to the Library itself.


Restriction on general use of the Library

  1. In addition to the terms imposed by the QPL, the Copyright's owner requires that if you use or distribute the Library, you are required to provide to DEIS and the rest of the Library's user community any bug fixes or other improvements that you make to the existing classes of the Library. Such changes should be communicated through any appropriate means to the library Copyright's owners.

  2. If you use the Library in source or object form for producing software that you distribute, you are required to include the following mention (or its translation into the language of the rest of the distribution, if other than English) in the documentation of your software, including textual documentation as well as online documentation, such as README, tutorials, and API references.

    "This product includes packages from the Windsurf Library, copyrighted by DEIS, used according to the terms of the Windsurf Library License. See and, for the license terms,".

  3. You are not allowed to use the name of DEIS to endorse or promote products derived from the Library without specific prior written permission of the Copyright's owner.

Referencing to the Library

In addition to the terms imposed by the QPL, the Copyright's owner requires that every public disclosure presenting any result obtained with the help of the Library state the name of the Library and the Copyright's owner, its principal authors, as well as cite the canonical Library reference listed at the top of the publications page. This is the usual, fair way of giving credit to contributors to a scientific result. In addition, it helps us justify our effort in developing the Library as an academic undertaking.

If you have written something on or with the help of the Library, it's required that you drop us a brief note of the publication, so that we can add your entry to the list of publications using the Library. We are interested in listing applications in as many fields as possible.

Choice of Law

Since the Copyright's owner carries out his research activity in the state of Italy, as a replacement for that provided in the QPL, the license is governed by the Laws of Italy. Disputes shall be settled by Bologna City Court.
