Web2.1 Optical Flow as Energy Minimization Optical flow has traditionally been treated as an energy min-imization problem which imposes a tradeoff between a data term and a regularization term. [Horn and Schunck, 1981] formulated optical flow as a continuous optimization prob-lem using a variational framework, and were able to esti- WebDec 1, 2024 · Abstract. We introduce optical Flow transFormer, dubbed as FlowFormer, a transformer-based neural network architecture for learning optical flow. FlowFormer tokenizes the 4D cost volume built from an image pair, encodes the cost tokens into a cost memory with alternate-group transformer (AGT) layers in a novel latent space, and …
