✨ fit_affine_xform_landmarks ✨

okay bestie, welcome to the fit_affine_xform_landmarks page from the Computational Morphometry Toolkit (CMTK) — that's the manual name right there, fit_aff...ndmarks(1), iykyk. it's a command-line tool, it's from CMTK, and it's here to make your landmarks line up. let's get into it 💖

🌸 NAME 🌸

fit_affine_xform_landmarks — Fit Affine Transformation to Landmarks

🦋 SYNOPSIS 🦋

fit_affine_xform_landmarks SourcePath TargetPath OutputXform

three positional args, that's it, slay. you hand it a source, a target, and where you want the transform to land, and it does the thing.

💜 DESCRIPTION 💜

so basically? it fits a linear affine transformation to a set of matched landmarks. you know, the landmarks you already paired up with each other. it finds the transform that takes you from one to the other. iconic. 👑

🎀 OPTIONS 🎀

Global Toolkit Options (these are shared by all CMTK tools)

okay so these ones are not special to us, every CMTK tool has them. they're the group chat regulars. 🫶

  • --help — dumps the list of basic command line options to standard output. the "what do I even do here" button.
  • --help-all — dumps the complete list, basic and advanced, to standard output. the full lore drop 📚
  • --wiki — spits out the list of command line options to standard output in MediaWiki markup. for your wiki girlies.
  • --man — writes man page source in 'nroff' markup to standard output. manpage-ception fr fr.
  • --version — writes the toolkit version to standard output. so you know what era you're in ✨
  • --echo — writes the current command line to standard output. it's giving "receipts" 🧾
  • --verbose-level <integer> — sets the verbosity level. pick your volume.
  • --verbose, -v — bumps the verbosity level up by 1. heads up: this one is deprecated, it's only still around for backward compatibility. 💀
  • --threads <integer> — sets the max number of parallel threads (for POSIX threads and OpenMP). let it cook in parallel 🔥

Main Options

  • --rigid — fit only a rigid, 6 degree-of-freedom transformation instead of a full affine. why would you do this? because it needs fewer landmarks and it makes less trict assumptions about where they are — like, three non-collinear landmarks are genuinely enough to get a rigid transformation out of it. small but mighty 💅
