The encoder processes individual frames whilst the decoder processes a temporal batch of adjacent frames. The proposed decoder can be used on top of any segmentation encoder to improve temporal consistency.As driving is a continuous process, the curve of temporal change of velocity should show a sort of continuity and smoothness. But the traditional map matching method doesn't consider the connection among the trajectory points and can probably break the continuity. The true velocity information can be undermined by the map matching method.The first module generates multiple spatial features, such as full-frame and keypoint features for each T frame of the video. Then, the temporal module allows us to extract temporal correlations of the spatial features between frames for both streams. As a final step, the spatial and temporal networks have been linked to bidirectionalcreate spatio-temporal action tubes. Because these methods treat video frames as a set of independent images, they can not exploit the temporal continuity of videos. Thus, their detection results are actually unsatisfactory.
