<div dir="ltr">Hi All,<br><br>I'd like to generate a new image by summarizing some
other images in the same dimensions.<br>So I generated a new image and a
std::list for the images iterators. (actually, I thought that this dynamic
container is the best way to mange an unknown number of images)<br><br>For now,
it isn't working because I don't know how to forward the image's iterator from
that vector. in other words, how do I do the same as: output_it++ from a
vector?<br><br>Here is my code:<br><br> typedef
itk::ImageRegionIterator
<ImageType>
iteratorType;<br> typedef
itk::ImageRegionConstIterator
<ImageType>
constIteratorType;<br><br> constIteratorType
first_it (first_img, first_img->GetRequestedRegion());
<br>
iteratorType
output_it (output_img, output_img->
GetRequestedRegion());<br><br>
std::list<constIteratorType> list;<br>
std::list<constIteratorType>::iterator it;<br><br>
list.push_back(first_it);<br><br> if
(second_img.IsNotNull())<br>
{<br> constIteratorType second_it
(second_img, second_img->GetRequestedRegion());
<br> list.push_back
(second_it);<br> }<br><br> //initialize all
the iterators at the begin of input images<br> for(it =
list.begin(); it < list.end(); it++)<br>
{<br>
it->GoToBegin();<br> }<br><br>
for(output_it.GoToBegin(); !output_it.IsAtEnd();
++output_it)<br>
{<br> for(it = list.begin(); it <
list.end(); it++)//move on the images and get at each iteration the pixel value
and insert to the new image<br>
{<br>
output_val = it->Get() + output_val; //get values from each image and
insert in the output
image<br> //
How do I forward the image's iterator from here
?????<br>
}<br>
<br>
output_it.Set(output_val);<br><br> }<br><br><br><br>Any
thoughts would be very welcome ...<br>Hila<br></div>
