1. Human Perception
7: Pattern Sensitivity

2. Harmonic Spatial Stimuli
M = mean level, a = contrast, f = spatial frequency

3. Receptive Field MTF

4. Harmonic Spatial-Temporal Stimuli
c(x,t) = M ( 1 + a sin(2fxx) sin(2ftt) )
M = mean level, a = contrast, fx = spatial frequency, ft = temporal frequency

5. Human Contrast-Sensitivity Function

6. Human Contrast-Sensitivity Function

7. Psychophysical Linespread Function

8. Light Adaptation

9. Light Adaptation (A) 2 degree disk (de Lange 1958)
(B) 60 degree disk (Kelly 1961)

10. Retinal Eccentricity (A) 1 degree x 2 degree grating patch
(B) Scaled in size and frequency

11. Retinotopic organization
