ANTsR (version 0.7.2.0)

composeTransformsToField: Compose arbitrary transform list into a deformation field.

Description

A deformation field can capture any domain to domain correspondence that we can represent in ANTsR. This function will map a list of transforms into a single deformation field object.

Usage

composeTransformsToField(image, transforms)

Arguments

image

input image defines the transformation domain

transforms

list of transform filenames or antrTransforms

Value

field deformation object is output

Examples

# NOT RUN {
fi <- antsImageRead(getANTsRData("r16") )
mi <- antsImageRead(getANTsRData("r64") )
fi<-resampleImage(fi,c(60,60),1,0)
mi<-resampleImage(mi,c(60,60),1,0) # speed up
mytx <- antsRegistration(fixed=fi, moving=mi, typeofTransform = c('SyN') )
compfield = composeTransformsToField( fi, mytx$fwd )
atx = antsrTransformFromDisplacementField( compfield )
wrped = applyAntsrTransformToImage( atx, mi, fi )
