Frequeny Analysis

Caption

Images of people transformed into the frequency domain: the upper left corner represents low-frequency image areas, the lower right corner represents high-frequency areas. On the left, you can see the transformation of a photo of a real person: the frequency range is evenly distributed. The transformation of the computer-generated photo (right) contains a characteristic grid structure in the high-frequency range - a typical artefact.
