WebWhile most previous methods focus on stereo and RGB-D images as input, few try to estimate scene flow directly from point clouds. In this work, we propose a novel deep neural network named F l o w N e t 3 D that learns scene flow from point clouds in an end-to-end fashion. Our network simultaneously learns deep hierarchical features of point ...
