vol_gamma — 3D gray op

• Data kinds: voxel → voxel

• Call: import volgray; volgray.vol_gamma(vol, gamma) (or ops3d.get("vol_gamma"))

Usage

Gamma (power-law) correction on the volume's own range (HALCON `pow_image`).

• 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)

• gray_window_level — py -3.11 examples_3d/gray_window_level.py
