Abstract
Method for processing of a grey scale image, in particular a dim grey scale image, comprising the following steps: a) receiving an initial grey scale image, said initial grey scale image having a plurality of pixels at an initial resolution, b) calculating parameters characterizing the luminance (gain, median_grey, var_grey) and the noise level (X, noise_estimate, radius_spatial_summation, grid_size, threshold_var) of the initial grey scale image of step a), c) creating a basic intermediate image, d) creating an averaged intermediate image, and e) creating an enhanced grey scale image by interpolation of pixels based on the averaged receptors (greyAvg) of the averaged intermediate image of step d).
