antsrMetricSetFixedTransform

set transform for fixed image

antsrMetricSetFixedTransform(metric, transform)

Arguments

metric

an 'antsrMetric'

transform

an 'antsrTransform'

Examples

x <- antsImageRead(getANTsRData("r16"))
y <- antsImageRead(getANTsRData("r30"))
metric <- antsrMetricCreate(x, y, type = "ANTSNeighborhoodCorrelation")
tx <- createAntsrTransform(precision = "double", type = "AffineTransform", dimension = 2)
setAntsrTransformParameters(tx, c(0, -1, 1, 0, 0, 0))
setAntsrTransformFixedParameters(tx, c(128, 128))
antsrMetricSetFixedTransform(metric, tx)
#> antsrMetric_SetTransform()
antsrMetricGetValue(metric)
