Diffeomorphic registration using b-splines
WebTo solve the scale change of tissue, we propose a scale adjustment method using the tissue area before and after registration. The experimental results demonstrate that our method can represent non-rigid deformation with a small number of control points, and is robust to a variation in staining. WebB-splines are commonly utilized to construct the transformation model in free-form deformation (FFD) based registration. B-splines become smoother with increasing spline order. However, a higher-order B-spline requires a larger support region involving ...

WebTo date, several deformable registration algorithms have been proposed and validated, including demons registration, viscous fluid registration, B-spline registration, and thin-plate splines. Performance results on a Tesla C1060 show that for large images, the GPU algorithm achieves a speedup of 15 times over a single-threaded CPU implementation.
