NAME

       landmark_warp - warp an image using point landmarks

SYNOPSIS

       landmark_warp [options]

DESCRIPTION

       The  landmark_warp executable performs registration by matching fiducials on reference and
       test images.  The list of possible options can be seen by typing:

       landmark_warp --help

       The command line usage is given as follows:

       Usage: landmark_warp [options]
       Options:
        -a, --algorithm <arg>         RBF warping algorithm {tps,gauss,
                                       wendland}
        -d, --default-value <arg>     Value to set for pixels with unknown
                                       value
            --dim <arg>               Size of output image in voxels "x [y z]"
        -F, --fixed <arg>             Fixed image (match output size to this
                                       image)
        -f, --fixed-landmarks <arg>   Input fixed landmarks
        -h, --help                    Display this help message
        -I, --input-image <arg>       Input image to warp
        -v, --input-vf <arg>          Input vector field (applied prior to
                                       landmark warping)
        -m, --moving-landmarks <arg>
                                      Output moving landmarks
        -N, --numclusters <arg>       Number of clusters of landmarks
            --origin <arg>            Location of first image voxel
                                       in mm "x y z"
        -O, --output-image <arg>      Output warped image
        -L, --output-landmarks <arg>
                                      Output warped landmarks
        -V, --output-vf <arg>         Output vector field
        -r, --radius <arg>            Radius of radial basis function (in mm)
            --spacing <arg>           Voxel spacing in mm "x [y z]"
        -Y, --stiffness <arg>         Young modulus (default = 0.0)

       Options "-a", "-r", "-Y", "-d" are set by default to:

       -a=gauss          Gaussian RBFs with infinite support
       -r=50.0           Gaussian width 50 mm
       -Y=0.0            No regularization of vector field
       -d=-1000          Air

       You may want to choose different algorithm:

       -a=tps            Thin-plate splines (for global registration)
       -a=wendland       Wendland RBFs with compact support (for
                          local registration)

       In the case of Wendland RBFs "-r" option sets the radius of support.

       Regularization of vector field is available for "gauss"   and  "wendland"  algorithms.  To
       regularize the output vector field increase "-Y" to '0.1' and up with increment '0.1'.
