In digital image processing, the banks are the watershed lines and the drainage areas are catchment basins. Watershed is the representation of the grayscale image as topographic relief. Watersheds with adjacent catchment basins are being built during the repeated flooding of the gray value relief. ...

" then it might look like the surface (left). With surfaces, it is natural to think in terms of catchment basins and watershed lines. The Image Processing Toolbox function watershed can find the catchment basins and watershed lines for any grayscale image. The key behind using the w...

The watershed transform algorithm used by this function changed in version 5.4 (R2007a) of the Image Processing Toolbox™ software. The previous algorithm occasionally produced labeled watershed basins that were not contiguous. If you need to obtain the same results as the previous algorithm, use...
