Remote Sensing Sparse-View 3D Gaussian Splatting via Depth Image-Based Rendering

Remote sensing novel view synthesis under sparse observations remains challenging due to insufficient geometric constraints and limited cross-view supervision. Existing Neural Radiance Fields (NeRF) and 3D Gaussian Splatting (3DGS) methods are prone to overfitting and face challenges of depth ambiguities, missing cross...

LoRetta: A Foundation Model and Extensive Dataset for Global-Scale Remote Sensing Dense Image Matching

LoRetta is proposed, a foundation model coupling matchability-aware affine localization with guided dense registration with LEVIR-GM, a global-scale multi-temporal optical matching benchmark with dataset-native matchability labels and establishes a unified evaluation protocol for sparse, semi-dense, and dense matchers.
