WebAdapter (CMA) to RAFT (Teed and Deng 2024). The RAFT model extracts feature map from each frame respectively for calculating the all-pair correlations. Our CMA utilizes the cross-attention of the input image pair, and predicts a ﬁlter to generate modal-adaptive feature maps for better cross-modal ﬂow estimation. WebIn this paper, we propose a Point-Voxel Recurrent All-Pairs Field Transforms (PV-RAFT) method to estimate scene flow from point clouds. Since point clouds are irregular and unordered, it is challenging to efficiently extract features from all-pairs fields in the 3D space, where all-pairs correlations play important roles in scene flow estimation. To tackle this …
