In this post we continue exploring and experimenting with topics from the PluralSight course Building Image Processing Applications Using scikit-image by Janani Ravi. The topic for this post is Watershed.

In image processing, a watershed (image processing) is a transformation defined on a grayscale image. The name refers metaphorically to a geological watershed, or drainage divide, which separates adjacent drainage basins. The watershed transformation treats the image it operates upon like a topographic map, with the brightness of each point representing its height, and finds the lines that run along the tops of ridges.
