Abstract:

In this paper we add some new experimental results to our recent work and discuss them with respect to human visual sensitivity for spatial frequency. In our experiment, several dot pattern images and sinusoidal gratings are used to probe the capabilities of the visual system.

We can see some characteristics of human perceptual system when we analyze our experimental results from the viewpoint of halftone dot size, shape and frequency.
