“…Optical Flow Estimation: Several deep architectures have been proposed for optical flow [4,8,23,29,30,38]. Among these, Recurrent All Pairs Field Transforms (RAFT) [30] have shown significant performance improvement over previous methods, inspiring many subsequent works [6,14,26,27,35]. Following the structure of RAFT architecture, complementary studies [12,14,33,35,39] proposed advancements on feature extraction, 4D correlation volume, recurrent update blocks, and more recently, transformer extensions [6,39].…”
