A method for determining a sharpness predictor for an input digital image includes determining one or more image metrics by analyzing the input digital image; and determining the sharpness predictor from the one or more image metrics.

Determining sharpness predictors for a digital image

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.
