In imaging science and computer vision, image processing is a technical analysis of the complex aspects of an image, deploying algorithms in which the input is an image, such as a photograph or video frame; the output of image processing may be either an image or a set of characteristics or parameters related to the image. Worldwide the ?eld of image processing is growing rapidly.An image can be corrupted by various kind of motion, noise or signal during the process of acquisition. To detect this motion or noise in the picture various method of restoration has been introduced in image processing. In general, the noise in the image is defined by the regions which are remarkably different i.e. darker or shiner comparing with the pixel with the neighboring pixels. To overcome this problem author ?rstly, focused on the causes of blur or corrupted image, among various method of restoration, emphasizes the neighboring pixel method, developed an algorithm for the restoration of an image by using distance transformation and mean method.An image (picture) can be thought of as being a function of two spatial dimensions: f(x, y). An image can be corrupted by various kind of motion, noise or signal during the process of acquisition. To detect this motion or noise in the picture various method of restoration has been introduced in image processing cite{lougheed1985neighborhood}. Image processing refers to the analysis and manipulation of a digitized image, especially in order to improve its quality. The Author emphasizes on solving identification problems primarily noticed in forensic medicine, or in creation of weather maps from satellite images. The bitmapped graphics format images that have been scanned in or shoted with digital cameras – which is used to deal with the reconstruction or enhancement of the uncorrupted image from a noisy one.A good number of filtering schemes such as Wiener filter, Bilateral filter, Bayseian based iterative method are developed over time for noise reduction and image restoration. The Median filter is one the filtering schemes that are widely used for noise reduction and also have applications in digital signal processing.
