Abstract
A noise filtering method including the steps of calculating a magnitude E.sub.i of density change for each of a plurality of linear direction components i in a local region around each of pixels of an inputted two-dimensional image, detecting such a direction as to minimize the magnitude E.sub.i of density change, conducting smoothing processing by deriving an arithmetic mean of densities of pixels in the local region arranged in the detected direction, and thereby reducing noise of the inputted image.
