Abstract--In this paper, an automatic head-shoulder
segmentation method for human photos based on graph cut with
shape sketch constraint and border detection through learning is
presented. We propose a new shape constraint method based
upon graph cut for head-shoulder photos. First, a watershed
algorithm is used to over segment the photo into superpixels; next,
an iterative shape mask guided graph cut algorithm with sketch
constraint is applied to the superpixel level graph to get a border
that segments the head-shoulder from its background; finally, a
