What is the integral of Gaussian function?

A Gaussian integral is essentially the area under the Gaussian function, between set limits along the horizontal axis.

What is a 2D Gaussian?

In fluorescence microscopy a 2D Gaussian function is used to approximate the Airy disk, describing the intensity distribution produced by a point source. In signal processing they serve to define Gaussian filters, such as in image processing where 2D Gaussians are used for Gaussian blurs.

What is the integral of a normal distribution?

Abstract. The integral of the standard normal distribution function is an integral without solution and represents the probability that an aleatory variable normally distributed has values between zero and . The normal distribution integral is used in several areas of science.
