Gaussian Filtering for Blurring
Gaussian Filtering for Blurring
In this Demonstration, the image is blurred using a Gaussian function. Gaussian filters are widely used to reduce the effect of noise and sharp details in the image. They are often used as a preprocessing stage in many algorithms in order to enhance the quality of images. Mathematically, when a Gaussian filter is applied to an image, essentially a kernel is convolved with the image using the pixel radius and the standard deviation .
