Abstract—
As the information from digital images are easier
to be evaluated as compared with one dimensional signals,
digital images are now commonly used in may research fields.
Unfortunately, similar to other digital signals, digital images
are also sometimes unintentionally corrupted by unwanted
signals, called noise. One of the noises commonly corrupting
digital image is the impulse noise. Therefore, impulse noise
reduction has become one of the active researches in these
recent years. Many impulse noise models have been proposed
by researchers for this research purpose. Therefore, the
purpose of this paper is to investigate the popularity of these
noise models. The research is done by a survey on available
online materials. However, because there are more than
thousands of related articles available online, the survey was
carried out based on the keywords related to those articles. The
research was restricted only to IEEExplore® database. The
result from this survey shown that the research related to
impulse noise model in digital image processing is still showing
an increasing trend. Among the impulse noise models, the saltand-
pepper noise is the most used impulse noise model in
current literature.
