The documentation below pertains to the approach presented in our ACMMM-2016 paper for analyzing part importance of category-epitomes, a novel visual representation for sketches developed by us.

To obtain the relative importance of semantic-parts in a given category, assuming a particular sketch stroke order, run the following MATLAB script:
get_epitome_part_stats_driverModify the above script by following the comments in the corresponding .m file (get_epitome_part_stats_driver.m)
To obtain a numerical characterization of semantic-part distribution histogram for a given sketch stroke ordering, run part_distribution_stats.m
Example :
part_distribution_stats('results','temporal')annotated-final : This is the directory containing the final set of sketch part contour annotations for the 13 object categories-original
results : This directory contains the per-category histogram of relative part importances for different sketch stroke orderings
160-pp/annotated-images : This directory contains the guideline images used by annotators while annotating sketch part contours
160-pp/categories-original : This directory contains selected object category images from the TU-Berlin sketch database (http://cybertron.cg.tu-berlin.de/eitz/projects/classifysketch/sketches_png.zip)
160-pp/categories-part-names : This directory contains part names for each category. It is for these parts that contour annotations are added on a per-object category basis.
