Abstract
We measured thresholds for the detection of spiral Glass patterns in the presence of random noise. The patterns were constructed so that the orientation content did not vary as a function of spiral angle or signal level. We found that spiral patterns had higher thresholds than either radial or concentric Glass patterns. The results support the idea that the human visual system is specialized to detect radial and concentric patterns.Entities:
