To address these issues and better exploit the spatio-temporal continuity of the lanes, we propose a novel Spatial-Temporal Lane3D model abbreviated as STLane3D. First, we propose a novel multi-frame pre-alignment layer under BEV, which uniformly projects features from different frames onto the same ROI region. Afterward, we propose a plug-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 ...PDF | On Jan 1, 2007, Olga Kochukhova published When, Where and What : The Development of Perceived Spatio-Temporal Continuity | Find, read and cite all the research you need on ResearchGateAbstract: In this paper, we propose a simple yet effective self-supervised method called spatio-temporal contrastive learning (ST-CL) for 3D skeleton-based action recognition. ST-CL acquires action-specific features by regarding the spatio-temporal continuity of motion tendency as the supervisory signal. To yield effective representations, ST-CL first designs some novel contrastive proxy tasks ...

The framework STGCN consists of two spatio-temporal convolutional blocks (ST-Conv blocks) and a fully-connected output layer in the end. Each ST-Conv block contains two temporal gated convolution layers and one spatial graph convolution layer in the middle. The residual connection and bottleneck strategy are applied inside each block.

Jun 8, 2015 · While the ASL is a fairly “chaotic” 2.7 seconds, the sequence builds perceptual spatio-temporal continuity through a series of contemplative spaces: at the point of revelation of the Transformer, the image holds in a medium-long shot, then dollies in just as the helicopter begins to transform.

The spatio-temporal continuity thesis: that a thing A is the same as the thing B if A and B are connected by a continuous path through space-time. What does temporal discontinuity mean? Temporal discontinuities are temporal positions marking a sudden breakage of projective identity. In this paper, we present a new tracking architecture with an encoder-decoder transformer as the key component. The encoder models the global spatio-temporal feature dependencies between target objects and search regions, while the decoder learns a query embedding to predict the spatial positions of the target objects.
