Rvision (version 0.4.2)

boxFilter: Blurs an Image Using a Box Filter

Description

boxFilter convolves the source image with the specified box kernel (a matrix of 1s). The result is a blurred version of the source image.

Usage

boxFilter(image, k_height = 5, k_width = 5, in_place = FALSE)

Arguments

image

An Image object.

k_height

The half-height in pixels of the kernel (default: 5).

k_width

The half-width in pixels of the kernel (default: 5).

in_place

A logical indicating whether the change should be applied to the image itself (TRUE, faster but destructive) or to a copy of it (FALSE, the default, slower but non destructive).

Value

An Image object if in_place=FALSE. Otherwise, it returns nothing and modifies image in place.
