Segments an input color or grayscale image into regions
with integer labels starting from an input "marker" image
giving initial labels

Algorithms
==========

    **Random walker**
        Segments grayscale or color image based on random
        walkers originating from labelled seed markers


        :beta: Penalization for random walker motion, larger values give less diffusion




    **Watershed**
        Floods watershed basins starting from the labels in the input marker image


        :compact: If not zero then use the compact-watershed algorithm
            giving more regularly shaped basins

        :line: Draws a one-pixel area with value=0 around each region
