gsm2d - 2D gaussian smoothing

Calling Sequence

MG = gsm(M [,sigma])

Parameters

Description

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

Examples

       initial_dir = PWD;
       chdir (SIPDIR + 'images');

       [Img,map] = imread('onca.gif');
       xbasc()
       imshow(Img,map);
       Img = im2gray(Img, map);     // Img is now 0-1 range
       xbasc()
       imshow(Img);
       Img = gsm2d(Img,2);
       xbasc()
       imshow(Img);

       chdir(initial_dir);
