An exemplary method for reducing noise in an image is disclosed. The image comprises a number of pixels including a current pixel that contains noise. The method comprises: measuring a value of each of the pixels; calculating a number of variances of value of a number of pixel areas, each of which includes the current pixel and lies in a unique orientation with respect to the current pixel, based on the measured values; calculating the mean of value of the pixel area associated with the current pixel and having the smallest variance of value, based on the measured values; and replacing the value of the current pixel with the calculated mean of value. |
