Title: The limiting effect of the human visual system on image processing
Author: Wilson, Timothy J.
Abstract: With the application of linear systems analysis, Fourier theory, and signal processing theory to vision science, the properties of the visual system are being defined in terms of such things as the modulation transfer function CMTF) . Earlier experimentation by other researchers has calculated the visual MTF using simple sine-wave targets. This experiment demonstrates the correlation between the visual MTF and the frequency content of simple images. The effect of image contrast is also shown to have an effect on the subjective evaluation of image sharpness. This experiment shows the need to consider the characteristics of the human visual system when digitally processed images are to be viewed.
