| gsm2d - 2D gaussian smoothing |
MG = gsm(M [,sigma]); |
| M |
| the matrix (intensity image) to be smoothed |
| sigma |
| the standard deviation of the gaussian kernel. Defaults to 5. |
| MG |
| the smoothed image. |
| Function gsm performs 2D gaussian smoothing of the image M, with standard deviation sigma, using FFT. |
