Image Registration with Local Rigidity Constraints

Registration is a technique nowadays commonly used in medical imaging. A drawback of most of the current registration schemes is that all tissue is being considered as non-rigid. Therefore, rigid objects in an image, such as bony structures or surgical instruments, may be transformed non-rigidly. In this paper, we integrate the concept of local rigidity to the FLexible Image Registration Toolbo...

Optimal Image Registration with a Guaranteed One-to-one Point Match

Projection Technique for Vortex-Free Image Registration

One important application of image processing in medicine is to register tissue samples onto another. Registering these highly textured images with non-parametric methods sometimes leads to solutions which are known to be suboptimal. We show a projection technique for unwanted vortices in the displacement field. A new strategy is presented which does not change the registration method itself bu...
