Removing Impulse Noise in Gray Scale Images using Min Max and Mid Point Filters
Main Article Content
Abstract
Images are frequently corrupted with impulse noise during acquisition and transmission. Noise should be removed while keeping the fine details of the image as one. More than a few algorithms have been projected to remove impulse noise from the corrupted images. So, in this paper we propose a new method called INR-method based on adoptive efficient Min-Max filter and Mid-point filter that can remove impulse noise from the corrupted gray-scale images. It is found that our experimental results are effective and efficient when compared to an Intelligent Recursive algorithm based on lifting filter.
