Amit K. Tripathi, Piyush Kumar Singh, Gaurav Shrivastava · 2014
Density Impulse Noise Removal method. Impulse noise is interference information pixels which result the black and white dots are spread distributed on the image. This type of noise can be caused by analog-to-digital converter errors, bit errors in transmission. Modified Mean-Median & ROM (MMM&R) filter that used to reduce impulse noise. Mean and Median filter are only applied for free-noise pixel on the 3x3 windows that has been sorted from the smallest to the largest value. Keywords-PSNR-peak signal to noise ratio, ROM-Rank order mean, MMM &R-modified mean median &ROM filter. I.
