In this paper a simple noise (Salt and Pepper) detection technique is proposed by using 3 x 3 sub-windows in which the test pixel appears. A weight is assigned to the test pixel based on its position after sorting in each sub-window. Two thresholds a

In this paper a novel algorithm for Gaussian noise estimation and removal is proposed by using 3x3 sub windows in which the test pixel appears. The standard deviation(STD) for all sub-windows are used to define reference STD(σref )and minimum(σmin)
