ABSTRACT
Facial affect is central to many VMC & affective computing applications, which often compress motion or frame-rate to reduce video bandwidth. Our studies show that claims that "categorical perception" effects protect facial affect from temporal degradation are illusory. Preserving motion is essential, even at the cost of image compression.

Categorical imperative NOT: facial affect is perceived continuously
CHI '04: Proceedings of the SIGCHI Conference on Human Factors in Computing SystemsFacial affect (or emotion) recognition is a central issue for many VMC and naturalistic computing applications. Most computational models assume "categorical perception" of facial affect, in which a benign illusion promotes robust recognition of ...
Categorical processing of negative emotions from speech prosody
Everyday communication involves processing nonverbal emotional cues from auditory and visual stimuli. To characterize whether emotional meanings are processed with category-specificity from speech prosody and facial expressions, we employed a cross-...
Categorical Perception of Happiness and Fear Facial Expressions: An ERP Study
Behavioral studies have shown that two different morphed faces perceived as reflecting the same emotional expression are harder to discriminate than two faces considered as two different ones. This advantage of between-categorical differences compared ...
