mia-2dfluid {-i io} {-r io} [ options ...]


This program is used for non-rigid registration based on fluid dynamics. For reference see

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.

It uses SSD as the sole registration criterion.



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

input (test) image to be registered. For supported file types see Plugin type: 2dimage/io

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

reference image. For supported file types see Plugin type: 2dimage/io

-o, --out-transformation=(output); io

output transformation comprising the registration. For supported file types see Plugin type: 2dvf/io

-d, --out-image=(output); io

output image deformed according to the transformation. For supported file types see Plugin type: 2dimage/io

Help & Info

-V, --verbose=warning; dict

verbosity of output, print messages of given level and higher priorities. Supported priorities starting at lowest level are:

debug:Debug output
message:Normal messages
info:Low level messages
error:Report errors
fatal:Report only fatal errors
trace:Function call trace
fail:Report test failures
--copyright=(); bool

print copyright information

-h, --help=(); bool

print this help

-?, --usage=(); bool

print a short help

--version=(); bool

print the version number and exit


--threads=-1; int

Maxiumum number of threads to use for processing,This number should be lower or equal to the number of logical processor cores in the machine. (-1: automatic estimation).

Registration parameters

-m, --mgstart=16; uint

multigrid start size

-e, --epsilon=0.001; float

optimization breaking condition

--mu=1; float

elasticity parameter

--lambda=1; float

elasticity parameter


use elastic registration


Register image test.v to image ref.v and write the deformation vector field regfield.v. Start registration at the smallest size above 16 pixel.

mia-2dfluid -i test.v -r ref.v -o regfield.v -s 16
