Efficient Graph-based 2D Image Segmentation

This Xtra implements efficient graph-based image segmentation by Felzenszwalb and Huttenlocher [1].

The new GraphBasedSegmentation module is stored in the category Xtra>Image Processing. It performs 2D, XY slice-by-slice  segmentation of the input grayscale image. You can use this form of segmentation to perform over-segmentation of grayscale images.

The project included in this Xtra demonstrates quick partitioning and labeling of a VolumeScope SEM image of a mouse brain to isolate objects that are circular or elliptical and that have relatively higher brightness compared to the other objects in the scene.
