Researchers have introduced the Flow Any Scene Transformer (FAST), a novel correspondence model designed for precise matching across images. FAST leverages insights from single-view vision foundation models, specifically their query-key projections, to initialize a ViT-based matcher. This approach allows the model to scale with advancements in single-view models without requiring dedicated pair-centric pretraining. FAST utilizes a zero-parameter rewiring strategy to convert self-attention layers into cross-attention for inter-view interaction and was trained on a 6-million-pair dataset. Experiments show FAST achieving state-of-the-art performance and favorable scaling with backbone size and training data. AI
