pool_band: This function is to be used in conjunction with...

In UBC-MDS/pictureperrrfect: Pictureperrrfect

Description

The function applies a lossy pooling algorithm to compress the specified colour band and the resulting cimg object is returned.

Usage

pool_band(img, kernel_size, pooling_func)

Arguments

img	A 'matrix' 'array' type object of 2 dimensions representing a color band of either a greyscale image or a colour image.
kernel_size	The size of the length and width of the kernel to be passed over the image. Default: 2
pooling_func	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)
pool_band(img[,,,1], kernel_size=2, pooling_func="max")
