至于flow warp error本身，据我所知，在无监督光流中是作为主要的learning loss，叫photo loss。另外，...
为了解决流场中模糊的流场边界和伪像问题,文章建议使用由特征驱动的局部卷积f-lconv对级联式流场推理的光流场进行规范化。 引入f-warp层:从前一级别的流场估计将F2向F1变形来构建成本量之前减少F1和F2之间的特征空间距离,即Feature Warping。 在Sintel和KITTI基准测试集上性能超过了SOTA方法FlowNet2,并且模型尺寸缩小25.3...

解决airflow 的问题Error: No module named 'airflow' 打开ubuntu启动airflow时发现报错 Error: No module named 'airflow.www' 网上查了一下,说是没有进入airflow路径,于是cd 进入airflow目录,结果报错Error: No module named 'airflow' 再上网查,说是权限问题,于是果断加sudo,成功!!!......
通过后向流操作可以有多个到达点,通过连续的warp process不断增加可达范围,即flow-warped occupancy的范围不断变大,并且不会移出到栅格外, 图中第一行箭头标注的地方可以看到agent 可直行也可掉头 flow warping process 没有使用 occupancy预测结果,但W_tWt需要乘上对应的occupancy预测结果O_t ...
