getCheckerboardKernel: Checkerboard kernel

In soundgen: Sound Synthesis and Acoustic Analysis

Checkerboard kernel

Description

Internal soundgen function.

Usage

getCheckerboardKernel(
  size,
  kernel_mean = 0,
  kernelSD = 0.5,
  plot = FALSE,
  checker = TRUE
)

Arguments

size	kernel size (points), preferably an even number
kernel_mean, kernelSD	mean and SD of the gaussian kernel
plot	if TRUE, shows a perspective plot of the kernel
checker	if TRUE, inverts two quadrants

Details

Prepares a square matrix size x size specifying a gaussian kernel for measuring novelty of self-similarity matrices. Called by getNovelty

Value

Returns a square matrix with size rows and columns.

Examples

kernel = soundgen:::getCheckerboardKernel(size = 64, kernelSD = 0.1, plot = TRUE)
dim(kernel)
kernel = soundgen:::getCheckerboardKernel(size = 19, kernelSD = .5,
  checker = FALSE, plot = TRUE)
kernel = soundgen:::getCheckerboardKernel(size = c(9, 45), kernelSD = .5,
  checker = FALSE, plot = TRUE)
kernel = soundgen:::getCheckerboardKernel(size = c(9, 45), kernelSD = .5,
  checker = TRUE, plot = TRUE)
