cmatrix.gaussian

cmatrix.gaussian()

Generate Gaussian square base matrix.

Can be used as a generator of differents gaussian “filter type” matrix using an additionnal function mapped to each value (to convolve self matrix for example).

Two mode are avaible :

• 0 => binomial distribution

• 1 => regular distribution

In case of regular distribution, you have to instance an odd sized matrix

Parameters	Type	Description
size	int	the size of the square gaussain generated
mode	int	1 : regular distribution 0 : binomial distribution
norm	int	1 : normalize the filter mask 0 : don’t normalize

Returns

Matrix

The generated gaussian matrix
