Abstract

The paper examines the relationship between human evaluation of the sharpness of an image and the objective degree of edge enhancement, defined in terms of a modulation transfer function derived from a physical light source and photographic materials. Human perception of the sharpness of the image was measured by the modified method of constant stimuli. The sharpness of the images of four pictures was correlated with the modulation transfer function expressed by information volume and photographic materials. The sample correlation coefficient was r = 0.83. Theoretical implications of less than perfect correlation between the human evaluation and physical units are thoroughly discussed.
