Researchers have introduced LoRetta, a novel foundation model designed for dense image matching in remote sensing applications. This model reformulates the problem into localization-and-registration, first identifying overlap and affine geometry before refining dense correspondences. LoRetta is accompanied by LEVIR-GM, a large-scale benchmark dataset featuring multi-temporal optical imagery and matchability labels across various resolutions and continents. In evaluations, LoRetta demonstrated superior performance over existing methods like RoMa v2, achieving a higher area under the curve and improved percentage of correct keypoints, while also reducing inference time.
