distanceSingleIteration

public BinaryFast distanceSingleIteration(BinaryFast binary,
                                          int i)
Performs a single thinning and colours the thinned pixels accordingly.
Parameters:
binary - The BinaryFast representation of the input image.
i - The grey-level with which to colour the thinned pixels.
Returns:
The BinaryFast representation of the thinned image.
