PriorCLIP: Visual-Prior-Guided Vision–Language Model for Remote Sensing Image–Text Retrieval

PriorCLIP is a visual-prior-guided vision–language model that organizes closed-domain and open-domain retrieval as two complementary realizations of the same learning principle, which introduces remote sensing scene knowledge as a visual prior, then uses this prior to adapt image and text representations to the availab...
