Abstract
Selection of a filter for filtering an image to achieve fast noise reduction while retaining picture details and edge sharpness begins by first determining the detail throughout the image. Detection of the image edges then occurs. Using the image detail and edge information, the filter properties are selected, including the number of filter taps and the filter strength.
