glszm: Gray level size zone matrix.

In joelcarlson/radiomics: 'Radiomic' Image Processing Toolbox

Description

glszm returns a gray level size zone matrix for a given matrix.

Usage

glszm(data, n_grey = 32, truncate = TRUE, ...)

Arguments

data	A numeric 2D matrix.
n_grey	an integer value, the number of grey levels the image should be quantized into.
truncate	Logical. Remove values for sizes that have no entries
...	Can be given verbose=FALSE to suppress output from the n_grey conversion.

Details

Can be visualized using image(glszm(data)). For visualization info see ?image.radiomics

Value

a matrix of dimension n_grey by region size, the GLSZM. The column names represent the region size, row names represent grey level, and the entries represent the count of how many times a given size of given grey level occur.
