In this paper, in contrast to the existing CNN+RNN or pure 3D convolution based approaches, we explore a novel spatial temporal network (StNet) architecture for both local and global spatial-temporal modeling in videos. Particularly, StNet stacks N successive video frames into a \\emph{super-image} which has 3N channels and applies 2D convolution on super-images to capture local spatial-temporal relationship.
