Interpolation Artefacts in Non-rigid Registration
Voxel based non-rigid registration of images involves finding a similarity maximising transformation that deforms a source image to the coordinate system of a target image. In orde...

C-Arm Distortion Correction Using Patient CT as a Fiducial
X-ray imaging is an extensively used intra-operative imaging modality because of its low cost and portability. These images have to be corrected for geometric distortion in order ...

A Segmentation Based Variational Model for Accurate Optical Flow Estimation
Segmentation has gained in popularity in stereo matching. However, it is not trivial to incorporate it in optical flow estimation due to the possible non-rigid motion problem. In t...
