Abstract: Unsupervised segmentation evaluation measures are usually validated against human-generated ground-truth. Nevertheless, with the recent growth of image classification methods that use hierarchical segmentation-based representations, it would be desirable to assess the performance of unsupervised segmentation evaluation to select the most suitable levels to perform recognition tasks. Another problem is that unsupervised segmentation evaluation measures use only low-level features, which makes difficult to evaluate how well an object is outlined. In this paper we propose to use four semantic measures, that combined with other state-of-the-art measures improve the evaluation results and also, we validate the results of each unsupervised measure against an image annotation algorithm ground truth, showing that using measures that try to emulate human behaviour is not necessarily what an automatic recognition algorithm may need. We employed the Stanford Background Dataset to validate an im age annotation algorithm that includes segmentation evaluation as starting point, and the proposed combination of unsupervised measures showed the best annotation accuracy results.
