create object that measures similarity between two images

antsrImageToImageMetric.Create(fixed, moving, type = c("MeanSquares",
  "MattesMutualInformation", "ANTSNeighborhoodCorrelation", "Correlation",
  "Demons", "JointHistogramMutualInformation"), fixed.mask = NA,
  moving.mask = NA, sampling.strategy = "none", sampling.percentage = 1)

Arguments

fixed

the fixed antsImage

moving

the moving antsImage

type

image metric to calculate

  • MeanSquares

  • Correlation

  • ANTSNeighborhoodCorrelation

  • MattesMutualInformation

  • JointHistogramMutualInformation

  • Demons

fixed.mask

mask for the fixed image

moving.mask

mask for the moving image

sampling.strategy

sampling strategy, default if full sampling

  • noneFull sampling

  • random

  • regular

sampling.percentage

percentage of data to sample when calculating metric

Value

value of image to image metric

Examples

x = antsImageRead( getANTsRData( 'r16' )) y = antsImageRead( getANTsRData( 'r30' )) metric = antsrImageToImageMetric.Create(x,y,type="MeanSquares")
