Design of Smart Filter for Impulsive Noise Cancellation in Images

Mihir Narayan Mohanty


Noise is nature inherent. It can affect any type of signal or noise at the time of acquisition. Impulsive is one of the noise which appears suddenly with the signal or noise. In this paper, we have considered the images affected by impulsive noise. A filter based on fuzzy logic is designed and it can suppress noise in any environment at any time. It is based on standard fuzzy rules if input is high then output is high or else if input is low then the corresponding output is also low. However the rules are utilized in adaptive manner based on the median of the pixels of the image. Results shows the performance of the proposed model. A comparison between different filters and proposed filter.
