Abstract

Primates are especially good at recognizing facial expression using two contrasting strategies—an individual diagnostic feature (e.g., raise eyebrows or lower mouth corner) versus a relationship between features. We report several novel experiments that demonstrate a profound role of grouping and segmentation—including stereo—on recognition of facial expressions.
