Hi ,

I am trying to convolute a huge gaussian kernel ([192,192]) with an
image array ([512,512]). of course, if i had all the time on earth, i
could use the convol routine.
can someone tell me how do i get it done faster by using fourier
transform?
more specifically,

smoothimage = raw convol image

= something in terms of fourier transform

please don't mind my excellent math skills.

thanks,
pravesh
