<div>Normally, to visit every pixel in an Image, you’d use an ImageRegionIterator, or ImageRegionConstIterator. The latter you’d use when you don’t want to or cannot modify the image.</div>
<div><br>
</div>
<div>ImageRegionIteratorWithIndex (and ImageRegionConstIteratorWithIndex) are, as Jim Miller said, optimized for reporting the index of the voxel currently referenced by the iterator.</div>
<div><br>
</div>
<div>A very common use would be to iterate through an image, but use the index to access another image’s voxels as well. Generally, you’d use an iterator for each image but there are cases — like when you only occasionally use the index to access another image
— where it makes sense not to bother with the second iterator.</div>

<div>Hello,<br>
<br>
</div>
What is the purpose of <a href="http://www.itk.org/Doxygen/html/classitk_1_1ImageRegionIteratorWithIndex.html">
ImageRegionIteratorWithIndex</a>? I didn't get the whole point from the documentation. Can you kindly just clarify it a bit?<br>
<br>
</div>
Thanks.<br>
