To develop an elastic image registration framework using approximating thin-plate splines that explicitly accounts for errors in anatomical landmark localization.
Formulated a functional minimization scheme generalizable across image dimensions and smoothness orders to accommodate both isotropic and anisotropic landmark errors.
Integrated discrete point landmarks and arbitrary edge points within a unified mathematical formulation encompassing affine transformations and interpolating splines.
Extracted landmarks semi-automatically using three-dimensional differential operators and evaluated the algorithm on 2D and 3D human brain tomographic scans.
Theoretical framework unified optimal affine transformations and interpolating thin-plate splines as specific constrained cases.
Qualitative experimental validation demonstrated robust, smooth elastic registration across 2D and 3D tomographic images of the human brain despite landmark extraction errors.
