write on the output of a ProcessObject such as a reader/filter. Instead you
must assign it to an image pointer and call DisconnectPipeline(). The code
would look like this if I’m not wrong. Note that there may be errors and
I didn’t even try it.<o:p></o:p></span></font></p>

<br>
I would like to update the content of an image. I read an <br>
image from a file and then this image is passed, as an <br>
argument, in the itkGrayscaleDilateFilter. The output of <br>
this filter is then modificated and passed again in the<br>
itkGrayscaleDilateFilter.How can I update the new content <br>
ok ReaderMk(see the code)?<br>
<br>
InputImageType::Pointer mk = InputImageType::New();<br>
mk = readerMk->GetOutput(); <br>
IteratorType mkIt( mk, mk->GetRequestedRegion() ); <br>
<br>
mkIt.SetDirection(0);<br>
<br>
grayscaleDilate->SetKernel( structuringElement );<o:p></o:p></span></font></p>
<div id=1eue>
<p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size:

for (int i =0; i<2; i++)<br>
{<br>
grayscaleDilate->SetInput( readerMk->GetOutput() );
//I would like to update the readerMk<br>
grayscaleDilate->Update();<br>
<br>
for ( markerIt.GoToBegin(); !
markerIt.IsAtEnd();<br>
