PERFORMANCE OF UNCORRUPTED PIXEL COUNT DECISION BASED FILTER FOR REMOVAL OF SALT AND PEPPER NOISE FROM DIGITAL IMAGE

Ramkumar, Rajesh, Sharmila

Abstract: Uncorrupted pixel count Decision Based Filter (UPCDBF) algorithm employed in the process of removal of noise densities and restoration of grey scale image Which are heavily corrupted by salt and pepper noise. The algorithm replaces the corrupted centre pixel by midpoint or median value based upon the noise free pixel count. This algorithm outperforms Standard median filter(MF) , Arithmetic median(AMF) and PSMF. The algorithm exhibits High PSNR value.

Keywords: Salt and pepper noise, uncorrupted pixel count decision based filter (UPCDBF)
