Registration and matching?

[ptran1203]

Thank you for your wonderful work. I'm looking for an point cloud matching algorithm like this, but is it different from point cloud registration ?

IMHO, the definitions are not strict, so both terms sometimes mean the same thing.

However, registration typically refers to the problem of computing the parameters (e.g. rotation and translation in the case of rigid registration) that align the two point clouds. This is often done though matching: finding correspondences between points in the two point clouds.
