Examples

fi <- antsImageRead(getANTsRData("r16"), 2)
mi <- antsImageRead(getANTsRData("r64"), 2)
fi <- resampleImage(fi, c(128, 128), 1, 0)
mi <- resampleImage(mi, c(128, 128), 1, 0)
mytx <- antsRegistration(fixed = fi, moving = mi, typeofTransform = c("SyN"))
jac <- createJacobianDeterminantImage(fi, mytx$fwdtransforms[[1]], 1)
# plot(jac)
