fit_zernike — 3D curvilinear op

• Data kinds: image2d → table

• Call: import match3d; match3d.fit_zernike(disk_image, n_max=6, device='cpu', nr=48, nt=72) (or ops3d.get("fit_zernike"))

• GPU: this op has a GPU path (device="cuda")

Usage

A disc image → Zernike coefficients (the polar-coordinate surface fit of optics and wavefront metrology). Returns {(n,m): coef}.

References (sample data, literature)

• 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.

Runnable examples (verified samples that actually call this op)

• curvilinear_proj — py -3.11 examples_3d/curvilinear_proj.py
