Oversegmentation Methods: A New Evaluation

摘要

Using superpixels instead of pixels has become a popular pre-processing step in computer vision. Currently, about fifteen overseg-mentation methods have been proposed. The last evaluation, realized by Stutz et al. in 2015, concludes that the five more competitive algorithms achieve similar results. By introducing HSID, a new dataset, we point out unexpected difficulties encountered by state-of-the-art oversegmentation methods.
