cog: Image Center of Gravity

In neurobase: 'Neuroconductor' Base Package with Helper Functions for 'nifti' Objects

Image Center of Gravity

Description

Find Center of Gravity of Image, after thresholding

Usage

cog(img, thresh = 0, ceil = FALSE, warn = TRUE)

Arguments

img	Object of class nifti
thresh	threshold for image, will find img > 0
ceil	Run ceiling to force integers (usu for plotting)
warn	Produce a warning if the image is empty after thresholding

Value

Vector of length 3

Examples

dims = rep(20, 3)
x = array(rnorm(prod(dims)), dim = dims)
img = nifti(x, dim= dims, 
datatype = convert.datatype()$FLOAT32, cal.min = min(x), 
cal.max = max(x), pixdim = rep(1, 4))
cog(img)
