Survey on Impulse Noise Suppression Techniques for Digital Images

Noise suppression from images is one of the most important concerns in digital image processing. Impulsive noise reduction is the most important aspect considered while acquiring a digital image. Images are often corrupted by impulse noise during transmission. Various approaches have been used in the past to reduce impulse noise from digital images in such a way that the important information of the images is preserved. This paper presents the review of various such techniques that have been used in the past for reduction of impulse noise from digital images.
