getCentroids: Convert an image to the geometric centroids of its signal

In stnava/itkImageR: Examples using Rcpp to interface R and ITK

Description

Reduces a variate/statistical/network image to a set of centroids describing the center of each stand-alone non-zero component in the image.

Usage

centroids<-getCentroids(  img  )

Arguments

img	the image to reduce to centroids - presumably some kind of statistical or network map
threshparam	thresholds the input image at mean( img[ img > 0 ] ) - threshparam * sdev( img[ img > 0 ] )
clustparam	ignore post-threshold clusters smaller than this value

Value

the centroids are output in matrix of size npoints by 3
