Claim One:
1. A method for detecting noise in an image, the method comprising the steps of: (a) applying a frequency transform to the image for obtaining a magnitude image in a frequency domain; (b) comparing a threshold value to values of the magnitude image for obtaining first thresholded values; (c) applying a regression to one or more thresholded values for obtaining an estimated best fit; (d) determining a correlation factor from the estimated best fit; (e) if the correlation is met, calculate a streak angle; (f) if the correlation factor does not met a predetermined value, applying a second threshold to the first threshold values to obtain second threshold values which are a subset of the first threshold values; and (g) repeating steps (c) through (f) until the correlation is met in step (e) or until a maximum reiteration of steps (c) through (f) is met.
