ABSTRACT:
A method for noise removal filtering is provided. The method includes selecting a characteristic of a test pixel, such as brightness, and comparing the brightness of the test pixel to the brightness of an adjacent pixel. The noise removal filtering is terminated if the test pixel brightness is equal to the adjacent pixel brightness, such that it can be determined that the test pixel has not been corrupted with noise data.
