Opencv watershed

WebYou can visit the CMM webpage on watershed to understand it with the help of some animations. But this approach gives you oversegmented result due to noise or any other irregularities in the image. So OpenCV implemented a marker-based watershed algorithm where you specify which are all valley points are to be merged and which are not. WebAs a result, OpenCV created a marker-based watershed method that allows you to select which valley points should be merged and which should not. It's a segmentation of an …
