In UBC-MDS/pictureperrrfect: Pictureperrrfect

Description

The function can be applied to a greyscale or colour image. The user passes a cimg type object (from the imager package) which is to be compressed and the resulting compressed cimg object is returned. The user can also specify the pooling algorithm to be used and the size of the kernel to apply over the image.

Usage

compression_perrrfect(img, kernel_size = 2, pooling_function = "max")

Arguments

img	A cimg type object of 4 dimensions representing a greyscale or colour image.
kernel_size	The size of the length and width of the kernel to be passed over the image. Default: 2
pooling_function	The pooling algorithm to be used. Three options: "max", "min", and "mean". Default: "max"

Value

A cimg type image of 4 dimensions representing a greyscale or colour image.

Examples

img <- imager::as.cimg(imager::boats)
compression_perrrfect(img, kernel_size=2, pooling_function="max")
