Constructor Detail

BinaryProcessor

public BinaryProcessor(ByteProcessor ip)

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.

Method Detail

skeletonize

public void skeletonize()

Uses a lookup table to repeatably removes pixels from the edges of objects in a binary image, reducing them to single pixel wide skeletons. Based on an a thinning algorithm by by Zhang and Suen (CACM, March 1984, 236-239). 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. There is a routine in 'user.p' that draws all 256 neighborhoods.
