Figure 2
(a) One-dimensional Gaussian {1/[(2π)1/2σ]}exp[−(xμ)2/2σ2] and (b) radially symmetric two-dimensional Gaussian [1/(2πσ2)]exp[−(xμ|2)/2σ2]. The mean is μ (one-dimensional)/μ (two-dimensional). The standard deviation is σ, which is half-width at ∼61% of the peak height. The variance is σ2. The full-width half-maximum (FWHM) = 2.35σ. The area (one-dimensional)/volume (two-dimensional) under the curve is 1.
