Effect of luminance noise on the object frequencies mediating letter identification

Effect of luminance noise on the object frequencies mediating letter identification

Purpose: To determine if the same object frequency information mediates letter contrast threshold in the presence and absence of additive luminance noise (i.e. noise-invariant processing) for letters of different size. Methods: Contrast thresholds for Sloan letters ranging in size from 0.9 to 1.8 lo...
