WebMar 28, 2011 · cvWatershed () takes two arguments Iplimage *src_image and CvArr* markers. Could anyone elaborate on the markers argument since I need to segment my image on the basis of my touch, so could the marker array be formed in realtime on the basis of my touch and then cvWatershed be called..? image-processing opencv image … WebImplements one of the variants of watershed, non-parametric marker-based segmentation algorithm, described in [Meyer92] Before passing the image to the function, user has to outline roughly the desired regions in the image markers with positive (>0) indices, i.e. every region is represented as one or more connected components with the pixel values 1, 2, 3 …
