downsampling an image ( by a factor ) using gaussian blur
down_sample_image( image, factor, gaussian_blur = FALSE, gauss_sigma = 1, range_gauss = 2 )
depending on the input, either a matrix or an array
matrix or 3-dimensional array where the third dimension is equal to 3
a positive number greater or equal to 1.0
a boolean (TRUE,FALSE) specifying if gaussian blur should be applied when downsampling
float parameter sigma for the gaussian filter
float number specifying the range of values for the gaussian filter

This function downsamples an image with the option to use gaussian blur for optimal output.
path = system.file("tmp_images", "2.jpg", package = "OpenImageR") image = readImage(path) dsamp = down_sample_image(image, factor = 2.0, gaussian_blur = TRUE)
