ImageForestingComponents
ImageForestingComponents[image]
finds a segmentation of image, returning an integer matrix in which positive integers label different components.
ImageForestingComponents[image, marker]
tries to find a segmentation into components that include pixels indicated by marker.
ImageForestingComponents[image, marker, r]
finds components that are connected at a pixel scale given by r.
Details
- ImageForestingComponents[image, marker] generates a graph-based segmentation of image, starting with the pixels specified by marker.
- In ImageForestingComponents[image, marker], marker can be given either as an image, a graphics object, or a list of points
in the standard image coordinate system, where x runs from 0 to image width and y runs from 0 to image height, and position 
corresponds to the bottom-left corner of the image. - Nonzero elements of marker are treated as weighted seeds for the segmentation.
- ImageForestingComponents produces a complete segmentation, assigning each pixel to a foreground component.
- ImageForestingComponents works with binary, grayscale, and arbitrary multichannel images.
- ImageForestingComponents[image, marker, r] generates a segmentation where pixels in each component are connected within the radius r. The default radius setting is 2.
- ImageForestingComponents[image, marker, {r1, r2}] specifies different radii in vertical and horizontal directions.
