Abstract
Methods, apparatuses and computer programs for image processing are provided. A sequence of images, in particular, is processed in this case. The images are subdivided into tiles and the tiles are transformed into the frequency domain. By evaluating the argument of the spectral density in the frequency domain, it is possible to identify and rectify disturbances which, for example, are caused by air disturbances (flickering).
