Selectivity of Face Aftereffects for Expressions and Anti-Expressions
Adapting to a facial expression can alter the perceived expression of subsequently viewed faces. However, it remains unclear whether this adaptation affects each expression independently or transfers from one expression to another, and whether this transfer impedes or enhances responses to a different expression. To test for these interactions, we probed the basic expressions of anger, fear, ha...
متن کاملFace analysis : identity vs. expressions
Facial images present important visual variations, due to several parameters. Here, we focus on the identity and expression parts. We study the hypothesis of (image-based) automatic separability of identity from expressions. Indeed, sign language speakers using videos need a tool able to offer anonymity to their sign productions and such a tool has to modify the part of the facial image carryin...
متن کاملFace Alignment Under Various Poses and Expressions
In this paper, we present a face alignment system to deal with various poses and expressions. In addition to global shape model, we use component shape model such as mouth shape model, contour shape model in addition to global shape model to achieve more powerful representation for face components under complex pose and expression variations. Different from 1-D profile texture feature in classi...
متن کاملOrientation Selectivity for Representing Dynamic Diversity of Facial Expressions
— This paper presents a representation method of facial expression changes using Adaptive Resonance Theory (ART) networks. Our method extracts orientation selectivity of Gabor wavelets on ART networks, which are unsupervised and self-organizing neural networks that contain a stability-plasticity tradeoff. The classification ability of ART is controlled by a parameter called the attentional vigi...
متن کاملPerception of emotional expressions is independent of face selectivity in monkey inferior temporal cortex.
The ability to perceive and differentiate facial expressions is vital for social communication. Numerous functional MRI (fMRI) studies in humans have shown enhanced responses to faces with different emotional valence, in both the amygdala and the visual cortex. However, relatively few studies have examined how valence influences neural responses in monkeys, thereby limiting the ability to draw ...
