If you take a photo in low light, and the resulting image has a lot of noise, Gaussian blur can mute that noise. Our gaussian function has an integral 1 (volume under surface) and is uniquely defined by one parameter $\sigma$ called standard deviation. Increasing the Gaussian blur radius will increase contrast. “It’s like laying a translucent material like vellum on top of the image,” says photographer Kenton Waltz. 3. As in any other signals, images also can contain different types of noise, especially because of the source (camera sensor).

This may sound scary to some of you but that's not as difficult as it sounds: Let's take a 3x3 matrix as our kernel. At the top of the screen, you’ll see a blue bar labelled Slide to adjust. Mask Weight Determines the strength of filtering, whereby MaskWeight = 1 would be an infinite weight of the high-pass filtered image that is added. We model the blur kernel as an anisotropic (elliptical) Gaussian kernel, specified by three parameters that control the strength, direction and aspect ratio of the blur. · Goals .
