16.08.2018 · OpenCV implemented a marker-based watershed algorithm where we specify which valley points are to be merged and which are not. It is not an automatic but an interactive image segmentation. The "marker-based" means labeling where the region is a foreground or a background, and give different labels for our object we know.

On the other hand, this Python module will give you a watershed segmentation even when you do not supply any seeds (or, marks, as I refer to them in the implementation here). So you could say that the user supplied marks (seeds) for this Python module are more for the purpose of creating new valleys in the topographic relief representation

02.11.2015 · The first step in applying the watershed algorithm for segmentation is to compute the Euclidean Distance Transform (EDT) via the distance_transform_edt function ( Line 32 ). As the name suggests, this function computes the Euclidean distance to the closest zero (i.e., background pixel) for each of the foreground pixels.
