• Download large_scale_ir.rar files and uncompress them in an appropriate directory.
  • The codes are tested under 64-bit Linux machines (they may not run on Windows machines). We provided compiled mex files for 64 bit machines but if they do not run, you have to compile some C/C++ programs. Follow the instructions given in README file.
  • Add the toolbox directory in the Matlab path.
  • You can run codes for UCMerced Land Use dataset to learn the use of package.
  • Follow the instructions given in README to reproduce the experimental results.
  • We could not upload some datasets because of size limitation. Please contact us if you are interested in other datasets.
