The ANALYSIS OF NOISE REDUCTION USING ADAPTIVE FUZZY SWITCHING MEDIAN FILTER

Abstract

The pictures in the advanced arrangement are generally corrupted by drive commotion which is because of the unexpected blunders in correspondence channels or electronic sensors. Most existing strategies fall flat at high clamor thickness. Here another versatile insertion procedure is foreseen for reclamation of exceptionally corrupted pictures by arbitrary esteemed drive clamor. This new method gives a more corrected preferred picture quality over the standard Versatile Middle Channel, Standard Middle Channel, Choice Based Calculation, Dynamic Exchanged middle Channel, Choice Based Un-symmetric Trimmed Middle Channel and altered Choice Based Un-symmetric Trimmed Middle Channel. The strategy anticipated is confirmed for its proficiency against various pictures and is found to give enhanced Pinnacle Motion to-Commotion Proportion. These detected “noise pixels” will then be subjected to the second stage of the filtering action, while “noise-free pixels” are retained and left unprocessed. Then, the
NAFSM filtering mechanism employs fuzzy reasoning to handle uncertainty present in the extracted local information as introduced by noise. Simulation results indicate that the NAFSM is able to outperform some of the salt-and-pepper noise filters existing in literature.
