WebThe consistent landmark-based, thin-plate spline (CL-TPS) image registration algorithm is designed to align the landmark points and minimize the consistency errors across the entire image domain. The CL-TPS algorithm is solved by minimizing the cost function given by WebI implemented the thin plate spline algorithm (see also this description) in order to interpolate scattered data using Python.. My algorithm seems to work correctly when the bounding box of the initial scattered data has an aspect ratio close to 1. However, scaling one of the data points coordinates changes the interpolation result. the gruff stuff eye balm
