Morphology

watershed = water + shed (opaque) = water + shed

The image-processing sense is a highly specialized technical metaphor based on the geographic term, so it is not predictable from 'water' and 'shed' alone.

Etymology

Watershed in image processing borrows the land meaning: the method treats a picture like a map and 'floods' low areas to separate regions, so the name shows it splits an image into parts like water dividing into rivers.
