Hallo. I am trying to do a gaussian filter using the matlab function H = FSPECIAL('gaussian',HSIZE,SIGMA). I need to do that the height of the gaussian is one (that is that the gaussian goes from zero to one)while the parameter SIGMA is varied to change the wide of the base. How could I do this? Else, I don't know the relationship between the parameter SIGMA and the wide of the base. Somebody could tell me how could I control the wide of the base of the gaussian to give the value I want in each case? Thank you all very much. Regards. |
