# mia-3dfluid(1)

Fluid dynamic 3D registration

## NAME

mia-3dfluid - Fluid dynamic 3D registration

## SYNOPSIS

**mia-3dfluid -i \<in-image\> -r \<ref-image\> -o \<out-transformation\> \[options\]**

## DESCRIPTION

**mia-3dfluid** This program is used for non-rigid registration based on fluid dynamics as described in:

Wollny, G. and Kruggel, F., 'Computational cost of non-rigid registration algorithms  based on fluid dynamics', IEEE Transactions on Medical Imaging, 11(8), pp. 946-952, 2002. ⟨https://doi.org/10.1109/TMI.2002.803113⟩

 It uses SSD as the sole registration criterion.

## OPTIONS

### File-IO

- \-i --in-image=(input, required); io

  input image\
    For supported file types see PLUGINS:3dimage/io

- \-r --ref-image=(input, required); io
