其中,Gconv(⋅)是一个图卷积层。图卷积递归网络(Graph Convolutional Recurrent Network, GCRN)[71] 将LSTM网络与ChebNet [21] 结合在一起。扩散卷积递归神经网络(Diffusion Convolutional Recurrent Neural Network, DCRNN)[72] 将提出的扩散图卷积层(方程18)结合到GRU网络中。此外,DCRNN采用了编码器-解码器框架来...
Spatial Graph Convolutional Neural Network: Spatial Temporal Modeling 上一节讲的是空间卷积操作,这里重新回到了时间层面,对于t时刻的结点 v_{ti}的邻居结点需要加上在时间点q上的 v_{qj} 满足的条件为 d(v_{ti}, v_{tj}) \leq K ,且满足时间关系 |q-t| \leq [\Gamma/2] (取整)。 \Gamma 是...
[TOC] Spatial-Temporal Graph Convolutional Network for Video-based Person Re-identification(CVPR2020) 行人重识别 行人重识别(Person Re-identification),简称为ReID,是利用计算机视觉技术判断图像或者视频序列中是否存在特定行人的技术。广泛被认为是一个图像检索的子问题。给定一个监控行人图像,检索跨设备下的该...
为了完成在 spatial temporal graph 上的卷积操作,我们也需要 the sampling function,and the weight function. 因为 temporal axis 的次序是显然的,我们直接将 label maplSTlST定义为: 3.4. Partition Strategies. 给定spatial temporal graph convolution 的高层定义,设计一种 partitioning strategy 来执行 the label ma...
Spatial-Temporal Synchronous Graph Convolutional Network STSGCN的核心思想是三点:1)在上一个时间步骤和下一个时间步骤将每个节点与自身连接起来,构建一个本地化的时空图。2)利用时空同步图卷积模块获取局域化的时空相关性。3)部署多个模块对时空网络序列的异构性进行建模。

It mainly consists of three parts: an ordinary differential equation-temporal convolutional network (ODE-TCN) module, a graph convolutional network-temporal convolutional network (GCN-TCN) module and an output module. The ODE-TCN module is composed of an integrator, a solver and a temporal ...
Specifically, we propose a spatial temporal graph convolutional networks based prediction network for skeleton based video anomaly detection. In other words, we build a normal graph describing graph connection of joints in normal data, where joints of abnormal events will be outliers of this graph. ...
