The benchmark uses colour textures from our large Prague colour texture database. The benchmark uses cutouts from the original textures (1/6 approximately) either in the original or subsampled version. The remaining texture parts are used for the separate test/training sets. The benchmarks use 114 colour/grayscale textures from 10 thematic classes. The BTF measurements are provided by courtesy of Prof. Reinhard Klein from the Bonn University.
