This program performs 2d image registration. Image alignment is
performed on a slice-by-slice basis for the input 3d+time dataset,
relative to a user specified base image.
** Note that the script @2dwarper.Allin can do similar things, **
** with nonlinear (polynomial) warping on a slice-wise basis. **
Usage:
2dImReg
-input fname Filename of input 3d+time dataset to process
-basefile fname Filename of 3d+time dataset for base image
(default = current input dataset)
-base num Time index for base image (0 <= num)
(default: num = 3)
-nofine Deactivate fine fit phase of image registration
(default: fine fit is active)
-fine blur dxy dphi Set fine fit parameters
where:
blur = FWHM of blurring prior to registration (in pixels)
(default: blur = 1.0)
dxy = Convergence tolerance for translations (in pixels)
(default: dxy = 0.07)
dphi = Convergence tolerance for rotations (in degrees)
(default: dphi = 0.21)
-prefix pname Prefix name for output 3d+time dataset
-dprefix dname Write files 'dname'.dx, 'dname'.dy, 'dname'.psi
containing the registration parameters for each
slice in chronological order.
File formats:
'dname'.dx: time(sec) dx(pixels)
'dname'.dy: time(sec) dy(pixels)
'dname'.psi: time(sec) psi(degrees)
-dmm Change dx and dy output format from pixels to mm
-rprefix rname Write files 'rname'.oldrms and 'rname'.newrms
containing the volume RMS error for the original
and the registered datasets, respectively.
File formats:
'rname'.oldrms: volume(number) rms_error
'rname'.newrms: volume(number) rms_error
