  1. Download Databases for research comparison:
    Download 10,000 test images (low resolution web-crawled misc database used in WBIIS);
    download 1,000 test images (test database used in SIMPLIcity paper)(zip);
    Due to growing demands and concerns of compliance to 'fair-use', we can no longer provide the larger databases for research use. Sorry for inconvenience.

    The databases should be used only for comparing algorithms, which can be considered as 'fair use' of the images and our metadata. You should not redistribute the images. You should reference to

  2. Download SIMPLIcity Software Package:
    If you are a government agency, an education institution, or a non-profit organization, we may offer you a FREE license of the SIMPLIcity system to run on LINUX or Solaris. Please contact Prof. James Wang by email to discuss details. At the moment, the C source code is not ready for public download. If you are commercial and would like to use SIMPLIcity, let us know and we will try to arrange to let you use.
