<p class="MsoNormal">You are correct that the ImportImageFilter does not copy the buffer. It does provide options for who owns the memory i.e. who delete the buffer, with the flag LetImageContainerManageMemory.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">You are use the ImageDuplicator to explicitly copy the image. Here is an example:<o:p></o:p></p>

<div>
<p class="MsoNormal" style="margin-left:.5in">From reading the ITK documentation & source code comments, it appears that the itk::ImportImageFilter does not allocate new pixel buffer for the image that it creates. It simply uses the buffer that's passed to
it via SetImportPointer(). Is this correct?<o:p></o:p></p>

<div>
<p class="MsoNormal" style="margin-left:.5in"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal" style="margin-left:.5in">If yes, is there a flag that I can set for the ImportImageFilter to allocate buffer for the output image? Or, should I use another filter to create a deep-copy of the image that's created by ImportImageFilter, to
ensure that the final output image is independent of the buffer passed to the ImportImageFilter?<o:p></o:p></p>
