gaussianFilter: Filter image.

In xhtai/cartridges: Algorithm to Compare Cartridge Case Images

Description

This function applies a low and high-pass Gaussian filter. The low-pass filter uses an 11 x 11 matrix with sigma = 6, and the high-pass filter uses a 149 x 149 matrix with sigma = 44. This is translated from code by Joseph Roth and Zach Richardson.

Usage

gaussianFilter(inputImage, nonBF)

Arguments

inputImage	image matrix
nonBF	binary matrix of the same dimensions as inputImage, where 1s indicate the non-breechface region.

Value

The image matrix after filtering.

Examples

## Not run: 
# first run this:
croppedExample <- cropBorders(removedExample, centeredExample$centeredPrimer)
# then
nonBF <- is.na(croppedExample)
processedExample <- gaussianFilter(inpaintedExample, nonBF)

## End(Not run)
