In imager: Image Processing Library Based on 'CImg'

Blur image isotropically.

Description

Blur image isotropically.

Usage

isoblur(im, sigma, neumann = TRUE, gaussian = TRUE, na.rm = FALSE)

Arguments

im	an image
sigma	Standard deviation of the blur (positive)
neumann	If true, use Neumann boundary conditions, Dirichlet otherwise (default true, Neumann)
gaussian	Use a Gaussian filter (actually van Vliet-Young). Default: 0th-order Deriche filter.
na.rm	if TRUE, ignore NA values. Default FALSE, in which case the whole image is NA if one of the values is NA (following the definition of the Gaussian filter)
