/**
 * High level interface for computing superpixels.  Superpixels are sets of connected adjacent pixels which belong.
 * They are intended to break the image up intelligently along object boundaries allowing for easier processing.
 * Each pixel in the output segmented image is assigned an integer label to identify which region in the image it
 * belongs to.  A region is a continuous connected set of pixels.
