<div>Hi everyone,</div>
<div> </div>
<div>I have a question about detecting boundaries of 2D shapes in a given 2D image. I have an input 2D gray scale image that has a couple of regions (segmented objects) in it. What I would like to do is get the points that comprise the boundary for each of these shapes.
</div>
<div> </div>
<div>So, the background of my image has a fixed value (0 or -1) and I would like to use that as a threshold.</div>
<div> </div>
<div>I was wondering if there is a filter in VTK that can do this or if someone knows what the best way to do something like this would be??</div>
<div> </div>
<div>Thank you for any help and suggestion you can give me.</div>
<div><br>Best,<br> <br> </div>
