  TASED-Net is a 3D fully-convolutional network architecture for video saliency
detection. It consists of two building blocks: first, the encoder network
extracts low-resolution spatiotemporal features from an input clip of several
consecutive frames, and then the following prediction network decodes the
encoded features spatially while aggregating all the temporal information. As a
result, a single prediction map is produced from an input clip of multiple
frames. Frame-wise saliency maps can be predicted by applying TASED-Net in a
sliding-window fashion to a video. The proposed approach assumes that the
saliency map of any frame can be predicted by considering a limited number of
past frames. The results of our extensive experiments on video saliency
detection validate this assumption and demonstrate that our fully-convolutional
model with temporal aggregation method is effective. TASED-Net significantly
outperforms previous state-of-the-art approaches on all three major large-scale
datasets of video saliency detection: DHF1K, Hollywood2, and UCFSports. After
analyzing the results qualitatively, we observe that our model is especially
better at attending to salient moving objects.
