abstract = "Superpixel segmentation can be defined as an image partition into
connected regions, such that image objects may be represented by
the union of their superpixels.In this context, multiple
iterations of superpixel segmentation from improved seed sets is a
strategy exploited by several algorithms. The Iterative Spanning
Forest (ISF) framework divides this strategy into three
independent components: a seed sampling method, a superpixel
delineation algorithm based on strength of connectedness between
seeds and pixels, and a seed recomputation procedure. A recent
work shows that object information can be added to each component
of ISF such that the user can control the number of seeds inside
the objects and so improve superpixel segmentation. However, it is
uncertain how the added information impacts each component of the
pipeline. Therefore, in this work, a study is conducted to
evaluate such inclusion in the seed sampling procedure, partially
elucidating its benefits. Additionally, we introduce a novel
object-based sampling approach, named Object Saliency Map sampling
by Ordered Extraction (OSMOX), and demonstrate the results for
supervised and unsupervised object information. The experiments
show considerable improvements in under-segmentation error,
specially with a low number of superpixels.",
