Face analysis : identity vs. expressions
نویسندگان
چکیده
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 carrying identity features without degrading expressive part, needed for comprehension. We present here models of the face space and how they can be used to anonymize facial images.

Impaired recognition of body expressions in the behavioral variant of frontotemporal dementia.
Progressive deterioration of social cognition and emotion processing are core symptoms of the behavioral variant of frontotemporal dementia (bvFTD). Here we investigate whether bvFTD is also associated with impaired recognition of static (Experiment 1) and dynamic (Experiment 2) bodily expressions. In addition, we compared body expression processing with processing of static (Experiment 3) and ...

متن کاملFace inversion decreased information about facial identity and expression in face-responsive neurons in macaque area TE.
To investigate the effect of face inversion and thatcherization (eye inversion) on temporal processing stages of facial information, single neuron activities in the temporal cortex (area TE) of two rhesus monkeys were recorded. Test stimuli were colored pictures of monkey faces (four with four different expressions), human faces (three with four different expressions), and geometric shapes. Mod...
متن کاملDistinct frontal and amygdala correlates of change detection for facial identity and expression
Recruitment of 'top-down' frontal attentional mechanisms is held to support detection of changes in task-relevant stimuli. Fluctuations in intrinsic frontal activity have been shown to impact task performance more generally. Meanwhile, the amygdala has been implicated in 'bottom-up' attentional capture by threat. Here, 22 adult human participants took part in a functional magnetic resonance cha...
متن کاملHolistic Processing Develops Because it is Good
In this paper, we investigate the question, “what are the best features for face identification?” Ullman et al. used mutual information as measurement of how good a feature is for a class [Ullman et al., 2002]. Their experiments suggested that features of intermediate complexity are best in tasks of face vs. non-face and cars vs. non-cars. We are interested in the tasks of face identification a...
