So it blurs the edges also, which we don't want to do Bilateral filter also takes a gaussian filter in space, but one more gaussian filter which is a function of pixel difference.. This is highly effective against salt-and-pepper noise in the images Interesting thing is that, in the above filters, central element is a newly calculated value which may be a pixel value in the image or a new value.. But the operation is slower compared to other filters We already saw that gaussian filter takes the a neighbourhood around the pixel and find its gaussian weighted average..

Blur is similar to the Gaussian Blur filter in PhotoShop; its presence in CSS and SVG means we can now achieve the same effects natively on the web.. Gaussian function of space make sure only nearby pixels are considered for blurring while gaussian function of intensity difference make sure only those pixels with similar intensity to central pixel is considered for blurring..
