Abstract
Described herein is a method for signal processing in which noise in an input signal comprising an intensity which is a function of at least a first coordinate and a second coordinate. A noise reduction or de-noising process is applied to the input signal in respect of the first coordinate to generate an intermediate de-noised signal. A second noise reduction or de-noising process is applied to the intermediate de-noised signal in respect of the second coordinate to generate an output de-noised signal. For each coordinate, noise reduction processes are applied in two directions, the results of these processes being averaged to provide the de-noised signals. Weighting is applied in accordance with the detection of an edge within the signal used as input in the de-noising process.
