uniform filter (convolution with uniform kernel)

uniform_filter(image, size, conv_mode = "same")

Arguments

image

matrix or 3-dimensional array where the third dimension is equal to 3

size

a 2-item vector specifying the horizontal and vertical dimensions of the uniform kernel, e.g. c(3,3)

conv_mode

the convolution mode should be one of 'same', 'full'

Value

depending on the input, either a matrix or an array

Details
