Hello to all,<br> I am trying to develop my first filter in itk using visualstudio2010 and
cmake. This filter devides my input image into neighborhoods of nine
pixels and finds their maximum value. I have made some changes in my .txx file, but I am still having some problems when I build the project and I would like some help:<br><br>#ifndef __itkmax_value_filter_txx<br>#define __itkmax_value_filter_txx<br>

Hi to all,<br><br> I am trying to develop my first filter in itk using visualstudio2010 and cmake. This filter devides my input image into neighborhoods of nine pixels and finds their maximum value. Then, this value is transfered to one pixel of my output image. I have written the following code, but I have some failures that I cannot understand. Could someone help me to overide my problems? Furthermore, I would like to know if it is possible to write my own filter only with .cxx and .txt files, like<i> <a href="http://www.itk.org/Wiki/ITK/Examples/Iterators/ConstNeighborhoodIterator" target="_blank">http://www.itk.org/Wiki/ITK/Examples/Iterators/ConstNeighborhoodIterator</a></i>. <br>
<br>Thanks<br><br></blockquote><div> </div></div>Can you describe the failures? Are they compiler errors? Crashes? Incorrect results?<br><br><div>David </div></div>
