[Insight-users] Lidar-toImage registration with Rigid3DPerspectiveTransform

[ruisheng wang]

Hi Luis,

Thank you very much for your replies. Do you have an example code showing
the process of Lidar-to-Image registration using
Mutual informaiton. I could not find examples for doing this. In the ITK
document, there is not an example showing
PointSetToimageRegistration, do you have an example code showing how to use
PointSetToImageregistration?

thanks a lot!
Ruisheng
