                         computer vision. Recently, a graph-based framework named ISF 
                         (Iterative Spanning Forest) was proposed to obtain connected 
                         superpixels (supervoxels in 3D) based on multiple executions of 
                         the Image Foresting Transform (IFT) algorithm from a given choice 
                         of four components: a seed sampling strategy, an adjacency 
                         relation, a connectivity function, and a seed recomputation 
                         procedure. In this paper, we extend ISF to introduce a unique 
                         characteristic among superpixel segmentation methods. Using the 
                         new framework, termed as Recursive Iterative Spanning Forest 
                         (RISF), one can recursively generate multiple segmentation scales 
                         on region adjacency graphs (i.e., a hierarchy of superpixels) 
                         without sacrificing the efficiency and effectiveness of ISF. In 
                         addition to a hierarchical segmentation, RISF allows a more 
                         effective geodesic seed sampling strategy, with no negative impact 
                         in the efficiency of the method. For a fixed number of scales 
                         using 2D and 3D image datasets, we show that RISF can consistently 
                         outperform the most competitive ISF-based methods.",
