Method Details

doWatershed

public static void doWatershed(SimpleImage ip,
 SimpleModifiableImage ipLabels,
 boolean conn8)

Apply a 2D watershed transform.

Parameters:

ip - image containing intensity information

ipLabels - image containing starting labels; these will be modified

conn8 - true if 8-connectivity should be used; alternative is 4-connectivity

doWatershed

public static void doWatershed(SimpleImage ip,
 SimpleModifiableImage ipLabels,
 double minThreshold,
 boolean conn8)

Apply a 2D watershed transform, constraining region growing using an intensity threshold.

Parameters:

ip - image containing intensity information

ipLabels - image containing starting labels; these will be modified

minThreshold - minimum threshold; labels will not expand into pixels with values below the threshold

conn8 - true if 8-connectivity should be used; alternative is 4-connectivity
