Abstract
A noise reduction method, medium, and system. The noise reduction method includes calculating a noise level of an input image and removing noise from a central pixel within a window of a predetermined size in the input image using a weight determined based on a difference between signal intensities of the central pixel and a plurality of adjacent pixels within the window and the calculated noise level.
