Abstract:
A method for processing of pixels of a first image segment, which has any desired shape, by a computer, comprising the steps of:providing first and second image segments each of a plurality of pixels; assigning the pixels of the first image segment a brightness value and/or a color value; extrapolating the brightness values and/or the color values of the first image segment onto pixels of a second image segment, which has any desired shape; carrying out the extrapolation in such a way that a signal profile of the brightness values and/or of the color values of the pixels of the second image segment is smoothed; carrying out the extrapolation in such a way that the signal profile of the brightness values and/or of the color values of the pixels of the second image segment is adapted to the brightness values and/or to the color values of the pixels of the first image segment in a boundary region between the first image segment and the second image segment; using a digital filter having a smoothing characteristic for the extrapolation; and using a local mean value filter as the digital filter, wherein the digital filter has the following filtering characteristics: S{xij}=Â¼(xiâˆ’1,j+xiâˆ’1,j+xi,j,+1+xi+1,j)â€ƒâ€ƒ(1) with xij being the respective pixel, and with i being the row index and j being the column index of the respective pixel.
