abstract = "We present an intelligent approach for understanding user
interaction to simplify the interface of graph-based image
segmentation. The user draws a set of markers (strokes) over the
object and the background, and our method automatically determines
a subset of these pixels with dissimilar image properties for
arc-weight estimation. Arc-weight estimation combines object
information learned from the set of selected pixels with image
information, to make object delineation more effective. Our method
differs from approaches that recompute the arc weights carelessly
during delineation, by further interpreting user interaction to
determine when and where to recompute them. Furthermore, we build
our framework around the image foresting transform (IFT), by
taking advantage of its operators for supervised fuzzy
classification, clustering, and object delineation. We evaluate
our framework using a dataset with 50 natural images and by
comparing it against another recent IFT-based method, which
computes arc weights in a separated step of user interaction for
more effective segmentation.",
