title: Image segmentation using ImageJ
body: <p>I'm using ImageJ and I want to implement my own function to segment a 2D binary image.<br>
  In order to do that I need to implement a region-growing function.<br>
  The first white pixel in my image is the seed indice.<br>
  Then I apply region-growing with an 4 connected neighbourhood mask.<br>
  Do you have some idea for the algorithm or an java code exemple ?</p>
