<html><head><meta http-equiv="Content-Type" content="text/html charset=utf-8"></head><body style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space;" class="">Hi,<div class=""><br class=""></div><div class="">I was thinking of adding a manual landmark based initialisation to my image registration method, as the automatic initialiser does not reliably work in my current application. I’m registering correlative microscopy images with very large shift and rotation between moving and fixed images — usually the moving image also covers only a small part of the area shown in the fixed image. By specifying the initial offset and rotation manually, registration works nicely, but this is a bit cumbersome, because I have to figure out the approximate offsets first.</div><div class=""><br class=""></div><div class="">The problem is that I do not seem to have the sitk.LandmarkBasedTransformInitializer() available in my SimpleITK version. It was used in the notebook <a href="http://insightsoftwareconsortium.github.io/SimpleITK-Notebooks/67_Registration_Semiautomatic_Homework.html" class="">http://insightsoftwareconsortium.github.io/SimpleITK-Notebooks/67_Registration_Semiautomatic_Homework.html</a>. I have SimpleITK 0.9.1 (Compiled Sep 28 2015) that I have installed on Anaconda according to the Wiki instructions. I am using Python 2.7. Would I possibly need some other version of SimpleITK? How could I get it? </div><div class=""><br class=""></div><div class="">Alternatively, is there some other simple method for calculating a spatial transformation from control point pairs in SimpleITK? I can of course do that in Numpy, but I wouldn’t like to overly complicate things.</div><div class=""><br class=""></div><div class="">Another question, in the notebook above you are using a visualisation module named “gui"<i class=""> </i>to show nice interactive plots, from which it is possible to make landmark selections as well. Is that by chance publicly available somewhere? </div><div class=""><br class=""></div><div class="">Best,</div><div class=""><br class=""></div><div class="">Sami<br class=""><br class="">
