BinaryProcessor
Creates a BinaryProcessor from a ByteProcessor. The ByteProcessor must contain a binary image (pixels values are either 0 or 255). Backgound is assumed to be white.

skeletonize
public void skeletonize(int foreground) Converts objects in a binary image with pixel values of 'forground' (255 or 0) to single pixel skeletons. Uses a lookup table to repeatably removes pixels from the edges of objects in a binary image, reducing them to single pixel wide skeletons. There is an entry in the table for each of the 256 possible 3x3 neighborhood configurations. An entry of '1' means delete pixel on first pass, '2' means delete pixel on second pass, and '3' means delete on either pass. Pixels are removed from the right and bottom edges of objects on the first pass and from the left and top edges on the second pass. A graphical representation of the 256 neighborhoods indexed by the table is available at "http://imagej.nih.gov/ij/images/skeletonize-table.gif".- Overrides:
