WebGaussian Smoothing. Common Names: Gaussian smoothing Brief Description. The Gaussian smoothing operator is a 2-D convolution operator that is used to `blur' images and remove detail and noise. In … WebJan 15, 2015 · The Gaussian Blur filter gives a hazy effect by blurring the image or selected area by an adjustable amount. This amount is based on a weighted average, also called The Gaussian Function . You’re able to implement the Gaussian Blur using either Radius or Threshold. The smaller the area you select, the less blur you’ll get.

In image processing, a Gaussian blur (also known as Gaussian smoothing) is the result of blurring an image by a Gaussian function (named after mathematician and scientist Carl Friedrich Gauss). It is a widely used effect in graphics software, typically to reduce image noise and reduce detail. The visual effect of this … See more Mathematically, applying a Gaussian blur to an image is the same as convolving the image with a Gaussian function. This is also known as a two-dimensional Weierstrass transform. By contrast, convolving by a … See more Gaussian blur is a low-pass filter, attenuating high frequency signals. Its amplitude Bode plot (the log scale in the frequency domain) is a parabola. See more This sample matrix is produced by sampling the Gaussian filter kernel (with σ = 0.84089642) at the midpoints of each pixel and then normalizing.
