vgeng − compute a Gaussian function

vgeng [if=infile] [of=ofile] [s=] [n=] [x=] [y=]

Vgeng generates a Gaussian function float image. The default standard deviation is 1.0 and default image size is 11 x 11 centered at (0,0). The Gaussian is scaled to have an area (volume) of 1.

s=sigma

set the value for sigma, the default is 1.0

n=

set the image size. The image dimensions are always odd (n is rounded down to the nearest odd number). The dfault size is 10 * sigma.

x=xsize

explicitly set the x image dimension. The same constraints as the n= option apply. A special case is setting x=1 which will create a 1-d Gaussian function.

y=ysize

explicitly set the y image dimension. The same constraints as the n= option apply.
