Is anyone know how to interpret the result of MultiResMIRegistration
(e.g. The Overall Transformation matrix and offset)?
If the rotation is measured between -1 and 1, then what
is the measurement of translation offset? by pixel or pixel size?
Where is the origin of the coordinate system?
What kind of coordinate system? Left-Hand/Right-Hand?
or something else?
I performed the MultiResMIRegistatin on the same image set
at different O.S. (Linux and Window2000), the result are different.
On Window 2000 the transformation matrix is
0.99951 -0.0148422 -0.0275434
0.0121688 0.995421 -0.94812
0.0288245 0.0944304 0.995114
Translation offset is:
-32.0531 63.969 -62.4461
On Linux the transformation matrix is:
0.999512 -0.0241558 -0.0198178
0.0223209 0.995862 -0.0880938
0.0218638 0.0876085 0.995915
Translation offset is:
-32.4999 60.1089 -54.4322
