Bilateral Filtering of Various Images for De-Noising Analysis

Abstract

Images are often humiliated by noises and noise is an unwanted disturbance which generally
occurs while capturing photos or when we transmit the image from one channel to another.
Removal of noise is an important task and it's depending on the noisy image, with this the
original image can be regenerated. While removing noise some time the details of the image
also get lost. Linear and Nonlinear filtering methods are mostly used to remove the noise,
from any image. With linear filters the edges of the given image get blur, but nonlinear
method preserves edges of the image and also reduce impulse noise. In this paper, a bilateral
filtering technique is used for removal of noise and it is a nonlinear method. With the help of
this method, we tried to remove noise from both colored and gray image. Range parameter
and spatial parameters are varied to obtain the desired results.
