GSM2D(1)

NAME
gsm2d - 2D gaussian smoothing

SYNOPSIS
MG = gsm(M [,sigma]);

PARAMETERS

M   the matrix (intensity image) to be smoothed

sigma
    the standard deviation of the gaussian kernel. Defaults to 5.

MG  the smoothed image.

DESCRIPTION
Function gsm performs 2D gaussian smoothing of the image M, with standard deviation sigma, using FFT.

EXAMPLE
initial_dir = PWD;
chdir (SIPDIR + 'examples');
[Img,map] = imread('onca.gif');
xbasc()
imshow(Img,map);
Img = im2gray(Img, map) / 257;   // Img is now 0-255 range
xbasc()
imshow(Img);
Img = gsm2d(Img,2);
xbasc()
imshow(Img);
chdir(initial_dir);
