<div dir="ltr">Hello, <div><br></div><div>I'm now working on a machine learning based 3D image registration work. To create the ground truth registration, I need to firstly using simple least square method to calculate a transformation from the corresponding point (I'm using RIRE datasets). </div>
<div><br></div><div>The same working flow in matlab and itk produced the same transformation matrix, but different transformed volume! In matlab, it's well aligned using the coordinates of control points given by RIRE dataset. But in ITK I have to inverse and switch the translation parameters. Then I realized it's because of the different coordinate system in itk and Matlab. </div>
<div><br></div><div>Can anyone tell me a method to convert transformation matrix calculated from the common coordinate system into the ITK one?</div><div><br></div><div>Thank you very much!</div><div><br></div><div>Best,</div>
