morph op• Data kinds: image2d × pairs × pairs → image2d
• Call: import fullseye as fs; fs.ledger.warp_tps_image(img, src_pts, dst_pts, lam=0.0, order=1) (to call the implementation directly, import imagemorph; imagemorph.warp_tps_image(img, src_pts, dst_pts, lam=0.0, order=1); from the registry, opsshape2d.get("warp_tps_image"))
Smooth warp that moves src_pts of img to dst_pts using a thin-plate spline.
Fits the inverse-mapping TPS from output coordinates → input coordinates (dst→src), evaluates it on the whole output grid, and samples. With lam=0 it corresponds exactly at the control points (features land correctly); lam>0 smooths the deformation. Smoother than piecewise affine, but at the cost of evaluating the kernel for all pixels × control points.
Arguments and return value are the same as warp_piecewise_affine.
