dilate: Mathematical morphology and filtering operations

Description

Mathematical morphology and filtering operations

Usage

dilate(image, kernel = NULL, ..., max = FALSE, nonzero = TRUE)
dilateall(image, kernel = NULL, ...)
erode(image, kernel = NULL, ..., min = FALSE)
filter_median(image, kernel = NULL, ...)
filter_mean(image, kernel = NULL, ..., norm = TRUE)
smooth_gauss(image, sigma)
subsample(image, offset = FALSE)

Value

An updated pipeline.

Arguments

image

An image object or pipeline.

kernel

A suitable kernel function (see kernels). If NULL, the most recently set kernel in the pipeline is used, if any, otherwise the default kernel (kernel_3d).

...

Additional arguments to the kernel function, if any.

max

Logical value: if TRUE, maximum filtering is used for dilation; otherwise mean filtering is used. Mean filtering is always used by dilateall.

nonzero

Logical value: if TRUE, the default, dilation is only applied to nonzero pixels/voxels. Otherwise it is applied everywhere (and maximum filtering is always used).

min

Logical value: if TRUE, minimum filtering is used for erosion; otherwise nonzero voxels overlapping with the kernel are simply zeroed.

norm

Logical value indicating whether the mean filter will be normalised or not.

sigma

Numeric value giving the standard deviation of the Gaussian smoothing kernel.

offset

Logical value indicating whether subsampled pixels should be offset from the original locations or not.
