How do you find the full width of a half maximum Gaussian?
The K-space gaussian filter has a HWHM (Half Width - Half Maximum) equal to the radius specified in Radius field. The FWHM (Full Width - Half Maximum) is simply equal to twice the radius. The values, g(r), of the gaussian filter are given for one dimension in Equation 1 for a radius = h and an image width of N pixels.
What is Gaussian half width?
The full width of the gaussian curve at half the maximum may be obtained from the function as follows. Let x=h at half the maximum height. Taking the natural log of both sides: The full width is 2h.
Why is full width half maximum?
The full width at half maximum (FWHM) is a parameter commonly used to describe the width of a "bump" on a curve or function. It is given by the distance between points on the curve at which the function reaches half its maximum value.
What determines the width of a Gaussian?
The standard deviation determines the width of the distribution.
