摘要:

行人轨迹预测是一个突出的研究方向,它已经朝着人群社交和上下文交互建模的方向发展,广泛使用长短期记忆(LSTM)来表示步行轨迹。现有的方法使用虚拟社区作为一个固定的网格,用于汇集行人的社会状态与调整过程,控制如何捕捉社会互动。这需要对特定场景进行性能定制,但降低了方法的泛化能力。在我们的工作中,我们部署了\textit{Grid-LSTM},这是LSTM的最新扩展,它在多维特征输入上运行。我们提出了一个新的视角,互动建模提出,行人社区可以成为自适应的设计。我们使用\textit{Grid-LSTM}作为一个编码器,了解潜在的未来社区和行人运动的视觉和空间边界的影响。我们的模型优于最先进的方法,这些方法在几个公开测试的监控视频中整理相似的特征。实验结果清楚地说明了我们的方法在场景特征和人群动态变化的数据集上的推广。

英文摘要:

Pedestrian trajectory prediction is a prominent research track that has advanced towards modelling of crowd social and contextual interactions, with extensive usage of Long Short-Term Memory (LSTM) for temporal representation of walking trajectories. Existing approaches use virtual neighborhoods as a fixed grid for pooling social states of pedestrians with tuning process that controls how social interactions are being captured. This entails performance customization to specific scenes but lowers the generalization capability of the approaches. In our work, we deploy \textit{Grid-LSTM}, a recent extension of LSTM, which operates over multidimensional feature inputs. We present a new perspective to interaction modeling by proposing that pedestrian neighborhoods can become adaptive in design. We use \textit{Grid-LSTM} as an encoder to learn about potential future neighborhoods and their influence on pedestrian motion given the visual and the spatial boundaries. Our model outperforms state-of-the-art approaches that collate resembling features over several publicly-tested surveillance videos. The experiment results clearly illustrate the generalization of our approach across datasets that varies in scene features and crowd dynamics.
