## Evaluation results averaged over each category in the Benchmark

Below are evaluation results each of the 19 object categories in the Benchmark. For every object category, each of the four bar charts shows a different evaluation metric computed for all seven algorithms and averaged across the entire data set. Added to each chart is a bar representing the human-generated segmentations evaluated with respect to one other (labeled "Human," on the left) and two bars representing trivial segmentation algorithms ("None" = all faces in one segment, and "Every"= every face in a separate segment). In all cases, lower bars represent better results.
