摘要： The present invention relates to a method and apparatus for reducing noise. A method of reducing noise according to an aspect of the present invention includes calculating a noise level of a reference pixel forming an input image, determining a weighted value to be allocated to the reference pixel based on similarity of a reference window including the reference pixel with respect to at least one comparative window existing in a comparative region of the input image and having the same size as the reference window, and the calculated noise level of the reference pixel, and filtering the input image using the determined weighted value.
