发明名称 Use of frequency transform in the analysis of image sensors
摘要 A method for detecting and removing noise from an image, the method includes the steps of applying a frequency transform to the image for obtaining a magnitude image; comparing a threshold value to values of the magnitude image for obtaining thresholded values; setting one or more thresholded values to a predetermined value; and reconstructing the image from the magnitude image having the predetermined values for removing noise from the image.
