invariantImageSimilarity: similarity metrics between two images as a function of geometry

Description

compute similarity metric between two images as image is rotated about its center w/or w/o optimization

Usage

invariantImageSimilarity(in_image1, in_image2, thetas,
  localSearchIterations = 0, metric = "MI", scaleImage = 1,
  doReflection = 0, txfn = "")

Arguments

in_image1

reference image

in_image2

moving image

thetas

numeric vector of search angles

localSearchIterations

integer controlling local search in multistart

metric

which metric MI or GC (string)

scaleImage

global scale

doReflection

reflect image about principal axis

txfn

if present, write optimal tx to .mat file

Value

vector of similarity values

Examples

# NOT RUN {
fi<-antsImageRead( getANTsRData("r16"))
mi<-antsImageRead( getANTsRData("r64"))
mival<-invariantImageSimilarity( fi, mi, c(0,10,20) )
# }
