doWatershed

public static void doWatershed(Mat mat,
 Mat matLabels,
 boolean conn8)

Apply a watershed transform.

Parameters:

mat - intensity image

 boolean conn8)

Apply an intensity-constrained watershed transform, preventing regions from expanding to pixels below a specified minimum threshold

Parameters:

mat - intensity image

matLabels - starting locations

minThreshold - minimum threshold

conn8 - if true, use 8-connectivity rather than 4-connectivity
