<div dir="ltr"><div><div><div>Dear Ruturaj,<br></div>if you don't need FLTK (as you mentioned, you don't need a GUI), then you need to modify the CMakeLists accordingly, i.e. remove all FLTK-related CMake variables in your new, fresh CMakeLists.txt<br>
<br></div>You will just need to tell CMake that your projects depends only on ITK.<br><br></div>In the ITK wiki, you will find quite a few examples on how to do this [1]. You even have a segmentation section there.<br><div>

<p class="MsoNormal" style="margin-bottom:12pt">Dear Ruturaj,<u></u><u></u></p>
</div>
<p class="MsoNormal" style="margin-bottom:12pt">1.- Haven't got the example with me, but if you intend to use a region growing segmentation filter a good point to start is the ITK software guide, chapter 9.1 [1]. There, you will be able to see which are the
available build-in algorithms/strategies, and you will see which are the methods you need to call in order to make them work. Please, bear in mind that segmentation is highly application-specific, and you may need to at least adjust the parameters, when it's
not to develop your own strategy based on what's available in ITK, for example. Nevertheless, the available examples in ITK are quite useful.<u></u><u></u></p>
</div>
<p class="MsoNormal" style="margin-bottom:12pt">2.- Sure. The seed point can be read from wherever you need (user interaction, program arguments, external file). The seed-setting method (or whichever method actually requiring the seed point) will only require
a vector/array or individual coordinates, regardless of where you picked up them.
<u></u><u></u></p>
</div>
<p class="MsoNormal">3.- As said, haven't got the app in front of me, but surely you will be able to build your own application for region growing segmentation without any GUI. ITK is independent of any GUI (now, the apps may use a specific one); you can just
build an application with the GUI library that you most like. Having said, that, may be the most common and easiest choice is Qt [2], which has an open source version.<u></u><u></u></p>
