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.
