An Efficient Denoising Algorithm for Detection and Removal of High-Density Impulse Noise from Digital Images
2015
Indian Journal of Science and Technology
Preserved Fulltext
In this paper an efficient denoising algorithm based on adaptive and unsymmetric trimmed median filter is proposed which effectively gets rid off the high-density salt and pepper noise. ...
Many of the existing algorithms do not preserve fine details of the image while removing noise at high noise densities. ...
Remove all the '255' value
from the whole image and calculate the midpoint for the
rest of the pixels), global midpoint value with only salt and
pepper noise trimmed (i.e. ...
