<div dir="ltr">Hi Gib.
<div><br>
<div>Thanks for the quick response. The problem of using dilation and skeletonization is that some times the gap between pixels is big, and I will have to work with different and big structural elements to be sure that all the gaps were eliminated.</div>
<div><br>
</div>
<div>I was hoping to find a class that works similar to a convex hull (it does not have to be convex) algorithm and then find the region surrounded by the hull.</div>

</div>
<div>Thanks</div>

<div style="direction:ltr; font-family:Tahoma; color:#000000; font-size:10pt">Sorry, I misread your post Fabian - I read it as you wanting the region _surrounding_ the white pixels. But dilate might be usable to fill the gaps, followed by skeletonization.<br>
