surface_residual — 3D freeform op

• Data kinds: image2d × image2d × image2d × bspline_surface → measurement

• Call: import bspline_surf; bspline_surf.surface_residual(x, y, z, tck) (or ops3d.get("surface_residual"))

Usage

Return the residual statistics between scattered data and a surface tck (the form error = the deviation from the fit).

• Sample-data catalog (download URLs / licences) — 2-D uses skimage.data (BSD/public domain) plus synthetic images; 3-D lists download URLs for real data sources (Stanford, PDS, …).

• Operator provenance and references — the sources of the research/methods this op family came from.
