This demonstration illustrate the difference between Gaussian and Bilateral filtering. As you move the mouse of the processed image, the left side of the image is unfiltered, the top right portion is Bilateral filtered, and the bottom right portion is Gaussian filtered. The parameters of the spatial Gaussian filters are kep the same between the Gaussian and Bilateral portions.
Move pointer over the lower image. As you move the mouse of the processed image, the left side of the image is unfiltered, the top right portion is Bilateral filtered, and the bottom right portion is Gaussian filtered. The parameters of the spatial Gaussian filters are kep the same between the Gaussian and Bilateral portions.
