Feb 07, 2017 · If this is a major problem when using segmentation to count objects in an image, the reader is referred to the book by Gonzalez, Woods and Eddins (2009) that describes marker-controlled watershed segmentation as an alternative method to avoid oversegmentation.
Nov 27, 2014 · The Initial Segmentation function uses the watershed transformation to determine the fiber edges, as it has become one of the most common and standard choices for image segmentation [22, 23]. However, the watershed transformation often leads to over-segmentation due to local minima created from noise within an image [ 24 ].

Wisconsin White Matter Hyperintensity Segmentation [W2MHS] and Quantification Toolbox is an open source MatLab toolbox designed for detecting and quantifying White Matter Hyperintensities (WMH) in Alzheimer’s and aging related neurological disorders. WMHs arise as bright regions on T2- weighted FLAIR images.
In graphs, watershed lines may be defined on the nodes, on the edges, or hybrid lines on both nodes and edges. Watersheds may also be defined in the continuous domain. There are also many different algorithms to compute watersheds. Watershed algorithms are used in image processing primarily for segmentation purposes.
