A1.04
Contrast sensitivity and spatial-frequency channels
Cards in this group · 5
- A1.04.1Discriminability is set by luminance contrast, not hue difference
- A1.04.2Contrast sensitivity varies with spatial frequency; thin strokes need higher contrast
- A1.04.3Contrast sensitivity declines with age and further in low light
- A1.04.4Texture segregation depends on local spatial-frequency differences, not color or luminance
- A1.04.5Two spatial-frequency channels can fatigue independently; blur compensation in one cannot substitute for the other
