Convert vector to multichannel antsImage.

Description

Converts a vector of size n-entries in mask times number of channels to a multi-channel image with the same dimensionality as the mask.

Usage

vectorToMultichannel(v, mask)

Arguments

v	input multichannel vector
mask	mask of same dimensionality as multichannelimage

Value

multichannelimage is output

Examples

fi <- antsImageRead(getANTsRData("r16")) %>%
  resampleImage(c(60, 60), 1, 0)
mi <- antsImageRead(getANTsRData("r64")) %>%
  resampleImage(c(60, 60), 1, 0)
mytx <- antsRegistration(fixed = fi, moving = mi, typeofTransform = c("SyN"))
mcimg <- antsImageRead(mytx$fwd[1])
msk <- getMask(fi)
vv <- multichannelToVector(mcimg, msk)
mcimg2 <- vectorToMultichannel(vv, msk)
vv2 <- multichannelToVector(mcimg2, msk)
cor.test(vv2, vv)
stopifnot(all(mcimg2[30, 30] == mcimg[30, 30]))
