ImageForestingComponents

ImageForestingComponents[image]
finds a segmentation of image, returning an integer matrix in which positive integers label different components.
ImageForestingComponents
tries to find a segmentation into components that include pixels indicated by marker.
ImageForestingComponents
finds components that are connected at a pixel scale given by r.
MORE INFORMATION
  • In ImageForestingComponents, 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 generates a segmentation where pixels in each component are connected within the radius r. The default radius setting is 2.
