iCAN: Instance-Centric Attention Network for Human-Object Interaction Detection

4 code implementations30 Aug 2018 Chen Gao, Yuliang Zou, Jia-Bin Huang

Our core idea is that the appearance of a person or an object instance contains informative cues on which relevant parts of an image to attend to for facilitating interaction prediction.

Learning to Generate Long-term Future via Hierarchical Prediction

2 code implementations ICML 2017 Ruben Villegas, Jimei Yang, Yuliang Zou, Sungryull Sohn, Xunyu Lin, Honglak Lee

To avoid inherent compounding errors in recursive pixel-level prediction, we propose to first estimate high-level structure in the input frames, then predict how that structure evolves in the future, and finally by observing a single frame from the past and the predicted high-level structure, we construct the future frames without having to observe any of the pixel-level predictions.
