✨ NAME ✨

pfstmo_ferradans11 — a tone mapping operator that does visual adaptation and local contrast enhancement, and honestly? she does both. 💅

🎀 SYNOPSIS 🎀

pfstmo_ferradans11 [--rho-r <val>] [--inv_alpha-a <val>] [--help]

🦋 DESCRIPTION 🦋

okay so this command runs a tone mapping operator, and it's the one described in this paper, bestie, quote it exactly:

S. Ferradans, M. Bertalmio, E. Provenzi and V. Caselles An analysis of visual adaptation and contrast perception for tone mapping. In: Trans. on Pattern Analysis and Machine Intelligence, 2011.

and here's the part that matters most — this operator does NOT need gamma correction. Not a little bit, not "eh maybe", it just doesn't. There's an example below showing you the way, so look at it before you go adding pfsgamma in there like it's nothing. 🫶

💅 OPTIONS 💅

• --rho-r <val>, -r <val> — this one controls the overall lightness (and it's tied to the adaptation level). Bigger value = brighter final image, simple as that. Default value: -4
• --inv_alpha-a <val>, -a<val> — this one controls the level of detail. The higher you go, the bigger the level of detail enhancement gets. Default value: 0.1
• --verbose — prints extra info while the program is running, if you're nosy like that (no judgement, I am too 👀).
• --help, -h — prints the list of commandline options. Classic. Iconic. Always there for you.

🌸 EXAMPLES 🌸

Tone map an image and save it out as png:

pfsin Tree.pfm | pfstmo_ferradans11  --rho -3 --inv_alpha 10 | pfsout tree.png

that's it, that's the whole pipeline — in through pfsin, toned through pfstmo_ferradans11, out through pfsout. ✨
