Sentence examples for using a rigid transformation from inspiring English sources
The triangulated meshes were then spatially aligned using a rigid transformation.
Registrations were performed using Elastix software [ 18] using a rigid transformation model (translations and rotations).
To correct the misalignment (translation and rotation) of the optic axes of the eyes caused by the neuromuscular blockage, we used a rigid transformation (a minimum square method) to adjust the coordinates of all RFs from one eye to the corresponding RFs from the other eye.
Subsequently, all volumes were realigned to correct for head motion, by using a rigid body transformation.
Images were then coregistered to the individual's T1 weighted image using a rigid body transformation and were normalized to the Montreal Neurological Institute (MNI) T1 reference brain template (resampled voxel size, 1.5 × 1.5 × 1.5 mm) using the DARTEL toolbox [ 31].
Decussation realignment: For each participant, the 3DT1w volume in diffusion space (obtained in step 2) was realigned along the superior/inferior direction to the MNI-152 template using a rigid body transformation (6 degrees of freedom) with nearest neighbour interpolation.
Functional images collected from the scanner were slice time corrected, aligned with a representative functional volume and motion corrected using a rigid body spatial transformation, morphed into the standard Montreal Neurological Institutes space, and spatially smoothed using a 4-mm full-width at half-maximum Gaussian kernel.
