antsrMetricCreate

Description

create object that measures similarity between two images

Usage

antsrMetricCreate(
  fixed,
  moving,
  type = c("MeanSquares", "MattesMutualInformation", "ANTSNeighborhoodCorrelation",
    "Correlation", "Demons", "JointHistogramMutualInformation"),
  fixed.mask = NULL,
  moving.mask = NULL,
  sampling.strategy = "none",
  sampling.percentage = 1,
  nBins = 32,
  radius = 3
)

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 none Full sampling random regular
sampling.percentage	percentage of data to sample when calculating metric
nBins	number of bins for histogram metrics (default = 32)
radius	radius for neighborhoo metrics (default = 3)

Value

value of image to image metric

Examples

x <- antsImageRead(getANTsRData("r16"))
y <- antsImageRead(getANTsRData("r30"))
metric <- antsrMetricCreate(x, y, type = "MeanSquares")
