Comparative Analysis of Methods Used to Remove Salt and Pepper Noise

In this paper, we will introduce a new method capable to remove or reduce salt and pepper noise (OPCLOSE method). The first phase of the method is to remove salt noise points by applying morphological image opening, while the next phase will remove the pepper noise points by applying morphological image closing. A comparative experimental analysis will be performed for various method of salt and pepper noise removal. The existing methods of salt and pepper noise removal such as based on pixel density filter method (BPDF), average filtering, median filtering, and other method. Salt and pepper noise removal method will be tested using noisy gray and color images, PSNR and MSE will be calculated in order to do some recommendation based on the on the calculated quality factors.
