Accident anticipation attempts to predict whether an accident may occur in advance, which is greatly significant for improving the safety of intelligent vehicles. Most existing approaches integrate the features of accident-relevant agents with spatial information for accident anticipation. However, these approaches ignore the actual spatio-temporal state of missing agents, whether they are ...

The thesis deals mainly with the first goal, although some aspects of the two others could be mentioned. To make the interpolation task feasible, a hypothesis on spatio-temporal continuity is required [1, 2]. That is, nearby measurements tend to be similar more than distant ones, which is known as Tobler’s law in geography .After spatio-temporal segments encoding and positional encoding of the skeleton sequence, the multi-headed self-attention mechanism can be used to model the relationship between input tokens. ...

Thus, we name it “Past-and-Future reasoning for Tracking” (PF-Track). Specifi-cally, our method adopts the “tracking by attention” frame-work and represents tracked instances coherently over time with object queries. In this paper, we present a unified, end-to-end trainable spatiotemporal CNN model for VOS, which consists of two branches, i.e., the temporal coherence branch and the spatial segmentation branch. Specifically, the temporal coherence branch pretrained in an adversarial fashion from unlabeled video data, is designed to capture the dynamic appearance and motion cues of video sequences to guide ...
