Method for determining the components of image noise patterns of an imaging device and use of this method in an imaging device |
摘要 |
<p>A method and a computer program for determining at least one component of a noise pattern of an imaging device. The method comprises the steps of: providing flat field data; forming a preliminary estimate of banding components by computing one-dimensional averages of the flat field data and carrying out a Fourier analysis of the one dimensional averages; determining the banding components by carrying out a two-dimensional Fourier analysis of the original flat field data, and comparing the result to the preliminary estimate; removing the banding components from the flat field data, to obtain modified flat field data; forming a second preliminary estimate of streaking components by carrying out a Fourier analysis on the modified flat field data; determining the two-dimensional random noise statistics by carrying out a Fourier analysis on the modified flat field data; and determining the streaking components by modifying the preliminary estimate of the streaking components with the two-dimensional random noise statistics. <IMAGE></p> |
