fill_holes — 3D `depth_denoise` op

• Data kinds: depth → depth

• Call: import fullseye as fs; fs.ledger.fill_holes(depth: 'np.ndarray', max_radius: 'float', *, invalid: 'float | None' = 0.0, max_iter: 'int | None' = None, rel_tol: 'float' = 1e-06) -> 'np.ndarray' (to call the implementation directly, import depth_bilateral; depth_bilateral.fill_holes(depth: 'np.ndarray', max_radius: 'float', *, invalid: 'float | None' = 0.0, max_iter: 'int | None' = None, rel_tol: 'float' = 1e-06) -> 'np.ndarray'; from the registry, ops3d.get("fill_holes"))

Usage

Interpolate invalid pixels (holes) from their valid neighbours by harmonic (Laplace) relaxation. → float64 (H,W).

各穴画素の最寄り有効画素までの距離が max_radius 以下なら補間対象、超える深い穴は補間せず NaN で残す

(fail-closed)。補間は 4 近傍平均の反復(Dirichlet 境界=元の有効画素)で、線形場(平面)は離散

調和関数の不動点なので反復収束とともに平面を厳密復元する。初期値は最寄り有効画素値(EDT)。

max_iter 既定は穴サイズに応じて自動設定、rel_tol は深度スケール相対の収束判定。全画素無効の入力は

補間の足場が無いため ValueError(fail-closed)。
