Hi, I'm currently testing out how well multi-resolution regristration works using the itk exampleapp. Currently I'm rotating 3d vtk images various degrees from 0 - 180. <br><br>I know Viola Wells has a requierment, in which the alignments need to be "close" together. In my tests, i noticed that specimens with over 90 degree rotations have a hard time converging to the right results.
<br><br>Currently I'm trying to give an estimated rotation, by initializing the transform with estimated parameters. Is this the correct way to get the images to register? Or should i simply play around with the scale parameters of the optimizer?
<br><br>Any suggestions would be appreciated.<br><br>Jonathan Wong<br>
