weingartenImageCurvature: image curvature for 3D

Description

uses the weingarten map to estimate image mean or gaussian curvature

Usage

weingartenImageCurvature(image, sigma = 1, opt = "mean")

Arguments

image

antsImage

sigma

smoothing parameter

opt

mean by default, otherwise gaussian or characterize

Value

image

Examples

# NOT RUN {
img = makeImage( c(10,10,10) , rnorm( 1000 ) )
fik <- weingartenImageCurvature( img )
if ( abs( mean(fik) - 128 ) > 1 ) stop("weingartenImageCurvature failure")
# }
# NOT RUN {
fi <- antsImageRead( getANTsRData( "mni" ) )
fik <- weingartenImageCurvature( fi )
# }
