jacobian_image: Image of the Determinant of the Jacobian

In neuroconductor/extrantsr: Extra Functions to Build on the 'ANTsR' Package

Description

Image of the Determinant of the Jacobian

Usage

jacobian_image(
  fixed,
  transformlist = NULL,
  moving = NULL,
  typeofTransform = "SyN",
  ...
)

log_jacobian_image(
  fixed,
  transformlist = NULL,
  moving = NULL,
  typeofTransform = "SyN",
  ...
)

geom_jacobian_image(
  fixed,
  transformlist = NULL,
  moving = NULL,
  typeofTransform = "SyN",
  ...
)

log_geom_jacobian_image(
  fixed,
  transformlist = NULL,
  moving = NULL,
  typeofTransform = "SyN",
  ...
)

Arguments

fixed	Fixed image in a registration
transformlist	List of transformation of moving image to fixed image. Only one of transformlist or moving should be specified.
moving	Image to transform into fixed space, if not done previously. Only one of transformlist or moving should be specified.
typeofTransform	If registration not done previously, then transform to use for transformation. Should be non-linear.
...	additional arguments to pass to registration

Value

An image of the determinant of the Jacobian, the transform list, and the fixed image.

Examples

library(extrantsr)
library(ANTsR)
library(methods)
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)
jac = jacobian_image(fixed = fi, moving = mi, verbose = FALSE)
## Not run: 
mytx<-antsRegistration(fixed=fi , moving=mi, typeofTransform = c("SyN") )
jac<-createJacobianDeterminantImage(fi,mytx$fwdtransforms[[1]],1)

## End(Not run)
