Hi Eleni,<br><br>I am back at work :).<br><br>Ok, we made several corrections to the code in the past two months and you can download the latest CVS version. Many thanks for your feedback on using the code. It helped us identify bugs and clean up the code further. <br>
<br>Your question was regarding the RMS Error values computed by the Dense and Sparse filters on the same image producing different values.<br><br>The dense filter works on the levelset function defined on the whole image domain. As a result, the RMS values are computed on changes in the function everywhere.<br>
<br>The sparse filter works only locally to the 0 level-set (hence the name sparse). The RMS values look at a small band of pixels. Therefore, the values in this case are at a different range.<br><br>Irrespective, the RMS values are used for indicating the convergence of the evolution. Is there any reason why you want them to be at the same range ?<br>

I hope everything went well concerning the embassy.<br>
Do you have any updates for the high RMS values? Was this problem fixed?<br>
<br>
