Fast Gaussian Filtering

Recursive gaussian filtering.

Description

A recursive implementation of the Gaussian filter. This implementation yields an infinite impulse response filter that has 6 MADDs per dimension independent of the value of sigma in the Gaussian kernel.

Recursive Gabor filtering for 1D and 2D signals. For more information please visit:

The function performs as advertised, with the following provisos:

1. It uses c++ style // comments. I had to edit the CFLAGS in mexopts.sh and remove the -ansi option to enable compilation (or you could just edit the file to remove them).

2. The function only works for type double images (other types generate an unhelpful segmentation fault).

When I run this code in Matlab then it gives error as " Error in ==> prova at 39
         y2=gaussian(ingresso,varianza,30);"
Can you please suggest this.

I even put the word " gaussian" in Matlab search and it did not give anything.
Please reply as early as possible.
