Bidirectional Entity Coupling Alignment for Fine-Grained Remote Sensing Image–Text Retrieval
Due to the homogeneous backgrounds and cluttered layouts of remote sensing (RS) imagery, fine-grained local entities are indispensable for preventing cross-modal semantic mismatch. However, existing parameter-efficient fine-tuning (PEFT) methods based on contrastive language-image pretraining (CLIP) encapsulate scenes...
