The images in the datasets are Copyrighted by the Victoria and Albert Museum in London and by the Visual Art Data Service. The Copyright allows for the use of these reduced images freely academic purposes. Also the images can be used for other purposes if the number of the images uses is less than 2000.

See the Victoria and Albert Museum website and the [Visual Art Data Service website}(http://vads.ac.uk/) for more detailed information.

To run the code several pieces of software are needed, all of them are available under a Copyleft or an Open Source Licence.

The following software packages are needed to run the experiments:

• ImageMagick 6.5.4-7 or later
• libsvm 3.18 or later
• python 2.6.6 or later (but not python 3)
• perl 5.8.8 or later
• bash 4.1.0 or later

Several extra modules for the Python programming language are needed as well, all of the can be installed from pypi:

• numpy 1.8.1 or later
• scipy 0.14.0
• matplotlib 0.99.1.1
• pillow 2.5.1 or later
• scikit-image 0.10.1
• ipython 1.0.0 or later
• pandas 0.14.1

The dataset acquisition phase of the work is not an automated process, yet several scripts were developed during that phase. The dependencies of those scripts are described below, shall one wish to try them:

• beautifulsoup4 4.3.2 or later
• pyyaml 3.10 or later
• git 1.5.0 or later is needed to clone unixjsons from its repository
• unixjsons 0.7 or later

Ensure that you have all dependencies described above installed and clone this repository into a directory on a file system that has at least 15GB of free space. Then go to src/

Acquisition and cleansing of the datasets is not covered because that process is not automated. To browse the code used to acquire the datasets go to the directories dataset-acquisition/vam and dataset-acquisition/nirp for the VAM and NIRP datasets respectively.

In src/ run the scripts that normalise, separate and filter the images before the extraction of features.

./step01-normalise.sh      # normalise to ~300 000 pixels
./step02-hsl-hsv.sh        # separates the channels
./step03-colourfulness.sh  # calculates the colourfulness
./step04-sobel.sh          # applies the Sobel filter
./step05-canny.sh          # applies the Canny filter
./step06-jpeg.sh           # compress the images

Next, run the feature extractors. These scripts print the calculated features to the standard output stream and log messages to the standard error stream, therefore redirect the standard output to files.

./step07-kolmogorov.sh     > fe/kolmogorov.dat
./step08-glcm.sh           > fe/glcm.dat
./step09-itten12.sh        > fe/itten12.dat
./step10-itten-contrast.sh > fe/itten-contrast.dat
./step11-rule-of-3.sh      > fe/rule-of-3.dat
./step12-img-averages.sh   > fe/img-averages.dat

A last feature script that generates the metadata (artist, school and country) of the image shall then be run. This metadata is what we classify against.

./step13-metadata.sh > fe/meta.dat

Map the features to a format compatible with LIBSVM and run the classifiers using the following scripts. The results of the classifiers are printed to the file cls/output.dat.

./step14-libsvm-format.sh
./step15-classify.sh

The last script combines the results from the classifiers with the file containing the feature values for all images (the horizontal concatenation of all .dat files) to produce the graphs and tables.

./step16-outputs.sh
