Hi,<br><br>Could someone solve some questions in program <i><a href="http://www.itk.org/Wiki/ITK/Examples/ImageProcessing/NthElementImageAdaptor" target="_blank">http://www.itk.org/Wiki/ITK/Examples/ImageProcessing/NthElementImageAdaptor</a></i> ? First, what exactly does the vec in imageIterator? Second, which element (pixel?) of image object is selected with the adaptor?<br>
<br>thanks<br></blockquote><div> </div><meta http-equiv="content-type" content="text/html; charset=utf-8">I added some comments - let me know if they clear up your concerns. The idea of the NthElementImageAdaptor is to allow a specified channel of a vector image to be accessed and used as if it were a scalar image without copying the memory.<br>
