The method involves passing the image data through a vertical high pass filter with limitation of amplitude to a set threshold. The filter output is then subject (4) to moving averaging and the filtered moving average is subtracted from the raw image. The high pass filter compares the current point with points in the corresponding vertical line of the image and subtracts the average luminance in t...
