<div dir="ltr">Hi Denis, <div style> Would you like to work on a <a href="http://www.itk.org/Wiki/ITK/Git/Develop">gerrit patch</a> from your Insight Journal submission code and merge it to ITK upstream ? I am sure many more other ITK community members could benefit from it. It might also make it easier to maintain your ITK projects.</div>
<div style> Once it is on gerrit, you could invite other ITK GPU expert to review it.</div><div style> Thank you!</div><div style><br></div><div style>-Xiaoxiao</div><div style><br></div><div style><br></div></div><div class="gmail_extra">
