Common Uses
Gaussian smoothing is commonly used with edge detection. Most edge-detection algorithms are sensitive to noise; the 2-D Laplacian filter, built from a discretization of the Laplace operator, is highly sensitive to noisy environments. Using a Gaussian Blur filter before edge detection aims to reduce the level of noise in the image, which improves the result of the following edge-detection algorithm. This approach is commonly referred to as Laplacian of Gaussian, or LoG filtering.

Famous quotes containing the word common:
“You know, what I very well know, that I bought you. And I know, what perhaps you think I don’t know, you are now selling yourselves to somebody else; and I know, what you do not know, that I am buying another borough. May God’s curse light upon you all: may your houses be as open and common to all Excise Officers as your wifes and daughters were to me, when I stood for your scoundrel corporation.”
—Anthony Henley (d. 1745)
“I have more in common with a Mexican man than with a white woman.... This opinion ... chagrins women who sincerely believe our female physiology unequivocally binds all women throughout the world, despite the compounded social prejudices that daily affect us all in different ways. Although women everywhere experience life differently from men everywhere, white women are members of a race that has proclaimed itself globally superior for hundreds of years.”
—Ana Castillo (b. 1953)
