WebWe introduce Optical Flow TransFormer (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 decodes the cost memory via a … WebMar 31, 2024 · The cost volume, capturing the similarity of possible correspondences across two input images, is a key ingredient in state-of-the-art optical flow approaches. When sampling for correspondences to build the cost volume, a large neighborhood radius is required to deal with large displacements, introducing a significant computational burden.
