摘要：The search for efficient noise removal methods from images is still a valid and serious challenge for the researchers. Clearing the noisy image is given the first priority before dealing with image processing algorithms on it. A plethora of existing algorithms are there and each of them has its assumptions, views, merits and demerits. All show an outstanding performance when the image model corresponds to the algorithm assumptions but fail in general and create artifacts or remove image fine structures. The paper lays focus on the review and comparative analysis of some important image noise removal techniques for reduction of impulse noise in time domain. This paper investigates a high-speed non-linear Order Statistic filter implementation as median filter. Then Adaptive Median Filter solves the dual purpose of removing the impulse noise from the image and redu cing distortion in the image. The Adaptive Median Filtering can achieve the filtering operation of an image corrupted with impulse noise up to 60%.
