Change detection is widely applied in remote sensing image analysis. Existing methods require training models separately for each dataset, which leads to poor domain generalization. Moreover, these rely heavily on large amounts of high-quality pair-labelled data training, expensive and impractical. In this paper, we propose a multimodal contrastive learning (ChangeCLIP) based visual-language pre-training change Additionally, dynamic context optimization prompt learning. Meanwhile, address...

Abstract Sufficient and accurate tide data are essential for analyzing physical processes in the ocean. A method is developed to spatially fit tidal amplitude phase lag along satellite altimeter tracks near Hawaii construct reliable cotidal charts by using Chebyshev polynomials. The completely dependent on data. By cross-validation method, optimal orders of polynomials determined polynomial coefficients calculated least squares method. amplitudes lags obtained compared with those from Finite...
