Thin-plate spline transformation
Web(1) Background: There was a need for 3D image reconstruction from a series of 2D projections in medical applications. However, additional exposure to X-ray projections may harm human health. To alleviate it, minimizing the projection numbers is a solution to reduce X-ray exposure, but this would cause significant image noise and artifacts. (2) Purpose: In … WebJan 30, 2024 · The default is R2LogR which is appropriate for 2D. Use R (SetBasisToR) if your data is 3D. Alternatively specify your own basis function, however this will mean that …
