Gamut — mask models
The on-device models behind Gamut's subject, sky and depth masks, kept here so every copy of Gamut downloads exactly the same, checksum-verified files. Gamut downloads a model only when someone chooses to use masks, and never sends a photograph anywhere: all of this runs on the person's own computer.
These are unmodified copies of the files named below. Each keeps its own licence and its authors' credit; nothing here is relicensed.
| File | What it does in Gamut | Model and authors | Copied from | Licence |
