A region growing based noise reduction method for digital images

摘要

A method for removing noise from a pixel of a digital image channel includes the steps of: storing an original value of the pixel of interest and using the value of the pixel of interest and neighboring contiguous pixels to determine a variable shape neighborhood region of cleaning pixels. The method further includes using the neighborhood region of cleaning pixels and the value of the pixel of interest to replace the original value of the pixel of interest with a noise cleaned pixel value.
