Flownet architecture
Web图中的F是光流估计网络，这里用的是改造过的flownet，输入相邻的两帧图片，得到和feature map大小一样的特征光流图，flownet已经在光流估计的数据集上预训练过。DFF在一段视频帧里面以固定间隔选取关键帧，其他的帧为非关键帧。 Below are the different flownet neural network architectures that are provided. A batchnorm version for each network is also available. 1. FlowNet2S 2. FlowNet2C 3. FlowNet2CS 4. FlowNet2CSS 5. FlowNet2SD 6.
