NAME
mia-3dfluid-syn-registration - Non-linear registration of 3D images by using a
diffeomorphic SyN registration
SYNOPSIS
mia-3dfluid-syn-registration -i <in-image> -r <ref-image> -o <transform> -O
<inverse-transform> [options]
DESCRIPTION
mia-3dfluid-syn-registration This program implements the registration of two gray scale 3D
images. The transformation applied is a symmeric diffeomorpic fluid dynamic registration.
To work most efficiently, this program makes a few assumptions about the imput data, i.e.
the image must be of the same size, have the same voxel spacing, and any intensity range
normalization or equalization should also be done before calling this program.

Processing
--threads=-1
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
-l --mg-levels=3
Number of multi-resolution levels to run the registration on. Not that some
registration parameters can be given as a coma seperated list to indicate
per level values. In these cases if the number of given values is smaller
than the number of multi-resolution levels (this parameter), the the last
given value is used for all subsequest multi-resolution levels.
-S --step=0.25; float in (0, 0.5]
Initial step size for all levels
-c --cost=ssd
Image similarity function to be minimized
For supported plugins see PLUGINS:3dimage/cost
-R --regularizer=sor:kernel=fluid,maxiter=50
Regularization for the force to transformation update
For supported plugins see PLUGINS:3dvf/regularizer
-T --conv-test-interval=; vuint in [4, 40]
Convergence test interations intervall: In order to measure convergence the
cost function value is averaged over this amount of iterations, and the
decline rate is evaluated based on the linare regression of the cost
function values in this intervall. This parameter can be given as a
coma-seperated list with values corresponding to the multi-resolution
levels, see option --mg-levels for more information.
-D --stop-decline-rate=; vdouble in [0, inf)
Stopping criterium for registration based on the cost decline rate. If the
rate below this value, the iteration is stopped. This parameter can be given
as a coma-seperated list with values corresponding to the multi-resolution
levels, see option --mg-levels for more information.
-C --stop-cost=
Stopping criterium for registration based on the cost value. If the cost
drops below this value, the iteration is stopped. This parameter can be
given as a coma-seperated list with values corresponding to the
multi-resolution levels, see option --mg-levels for more information.
-I --iter=; vuint in [4, inf)
Naximum number if iterations done on each multi-resolution level. This
parameter can be given as a coma-seperated list with values corresponding to
the multi-resolution levels, see option --mg-levels for more information.
