Paper Abstract

The relative effects of spectral amplitude and phase errors on reconstructed images are studied in terms of the expected mean-square-error in the image. An appropriate mean-square-error appears to be that between reconstructed and original images that are scaled to have the same energy. Such an error metric appears to reflect the overall perceived quality of the images. Approximate relationships between spectral amplitude and phase errors that give rise to the same image mean-square-error are derived. For large amplitude errors saturation is significant and is studied by simulation. Simulations are used to illustrate these relationships. The relationship to phase dominance is discussed.
