resize an image using the 'nearest neighbors' or the 'bilinear' method

Usage

resizeImage(image, width, height, method = "nearest", normalize_pixels = FALSE)

Arguments

image

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

width

a number specifying the new width of the image. Corresponds to the image-rows.

height

a number specifying the new height of the image. Corresponds to the image-columns.

method

one of 'nearest', 'bilinear'

normalize_pixels

a boolean. If TRUE, then the output pixel values will be divided by 255.0

Value

depending on the input, either a matrix or an array
