Stacked Spatio-Temporal Graph Convolutional Networks for Action Segmentation

no code implementations26 Nov 2018 Pallabi Ghosh, Yi Yao, Larry S. Davis, Ajay Divakaran

We show results on CAD120 (which provides pre-computed node features and edge weights for fair performance comparison across algorithms) as well as a more complex real-world activity dataset, Charades.

Human Body Model based ID using Shape and Pose Parameters

no code implementations6 Dec 2023 Aravind Sundaresan, Brian Burns, Indranil Sur, Yi Yao, Xiao Lin, Sujeong Kim

We show that when our HMID network is trained using additional shape and pose losses, it shows a significant improvement in biometric identification performance when compared to an identical model that does not use such losses.
