其中\omega_0为O_0通过真实输入得到: 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occupa...

WarpingInterpolationB-splinesOne of the fundamental problems in computer vision is to attain the apparent motion in image sequences, the optical flow. As evaluations at hand of recent benchmarks show, this field is highly competitive. High ranking variational methods often consist of a combination ...
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...
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倍,推理速度快3.1倍。GTX1080显卡上的光流估计帧率达到25。
PWC-Net是根据简单而完善的原则设计的:pyramidal processing, warping, and the use of a cost volume。在可学习的特征金字塔中,PWC-Net使用当前光流估计来warping第二幅图像的CNN特征。然后,它使用warping的特征和第一图像的特征来构建代价空间,该代价空间由CNN处理以估计光流。
2)开发了一种 stacked 架构,其中包括对第二幅图像进行中间光流 warping 处理。 3)通过引入一个专门处理小运动的子网络来详细说明小位移问题。 FlowNet 2.0只比原始 FlowNet 稍微慢一些,但估计误差却减少了 50% 以上。 它的性能与最先进的方法相当,同时还能以交互式帧速率运行。此外,我们还提出了速度更快的变体,...
