difference about 'grabcut' and 'lazysnapping'

Hello I learned the 'lazysnapping' is an advanced method from graph cut segmentation technique, and its combined graph cut and boundary editing. But from the function of 'lazysnapping', I cannot find the plugin of boundary editing. (BW=lazysnapping(A, L, foremask, backmask) Could anyone tell me what is the difference of function 'grabcut' and 'lazysnapping'. Thank you.

Lazy Snapping requires the user to specify foreground and background seeds, and performs 2D segmentation with the seeds as hard constraints. GrabCut makes the process more automatic by using iterated graph cuts – the only user interaction required is a bounding box of the foreground object.
