In the Eye of Transformer: Global-Local Correlation for Egocentric Gaze Estimation

no code implementations8 Aug 2022 Bolin Lai, Miao Liu, Fiona Ryan, James M. Rehg

To this end, we design the transformer encoder to embed the global context as one additional visual token and further propose a novel Global-Local Correlation (GLC) module to explicitly model the correlation of the global token and each local token.
