Correlates of facial expressions in the primary visual cortex, Trabalho apresentado em BCCN2009, In Proc. Bernstein Conf. on Computational Neuroscience (BCCN 2009). Abstract in: Frontiers in Computational Neuroscience, Frankfurt am Main, Germany, 2009.AUT: JRO00913; DUB00865;http://hdl.handle.net/10400.1/878Face detection and recognition should be complemented by recognition of facial expression, for example for social robots which must react to human emotions. Our framework is based on two multi-scale representations in cortical area V1: keypoints at eyes, nose and mouth are grouped for face detection [1]; lines and edges provide information for face recognition [2].engVisão humanaconference object2011-12-05
