WebWatershed IF erosion cycles: this is the amount of erosion cycles (in pixels) that are performed during a watershed, a seperator line cannot be longer than twice the erosion cycles. convexity threshold If this value is above "0" the erosion cycles are ignored. Particles that have a convexity below this value are watershed, others are not.
WebAn ImageJ plugin to apply watershed segmentation on graylevel images Written by Daniel Sage at the Biomedical Image Group, EPFL, Switzerland Outline This Java plugin is able to segment an image using the watershed algorithm by directly flooding graylevel images. WebWatershed algorithms are used in image processing primarily for object segmentation purposes, that is, for separating different objects in an image. This allows for counting the objects or for further analysis of the separated objects. Relief of the gradient magnitude Gradient magnitude image Watershed of the gradient
