utild2filt: Gaussian Filter for Matrices

Description

The function is applied to a pair of matrices as a lowpass 2d gaussian filter to clean them from high frequency components

Usage

utild2filt(d2arr0, d2arr1, outsize = 2, strong = 1)

Arguments

d2arr0

vector to be filtered

d2arr1

vector to be filtered

outsize

radius of gaussian filter kernel

strong

multiplication factor defining the sigma of gaussian filter kernel as sigma=outsize*strong

Value

filt0

matrix being the result of d2arr0 filtration

filt1

matrix being the result of d2arr1 filtration
