As seen from Figure 1B, we can see that the model predicts superior performance at low external noise levels for individuals with larger internal noise, possibly explaining superior performance reported in ASDs on some tasks, and possibly in higher vs. lower AQ groups (in TD … WebTo develop a psychophysically-based light reflection model for image synthesis we first need to understand the nature of gloss perception. In his classic text, Hunter [Hunt87] observed that there are at least six different visual phenomena related to apparent gloss. He identified these as: Figure 1: Coffee mugs with different gloss attributes.
