Every times the algorithm outputs a value, the window Sxy is moved to the<br />

EXPERIMENTAL RESULTS AND ANALYSIS<br />
The adaptive median filter is designed to remove impulsive noise from<br />
images. Therefore, our algorithm’s performance was first tested with basic salt<br />
and pepper noise with a noise density of 0.35.<br />
