Convolutional Neural Networks(CNNs) are data-driven methods that automatically extract the rich information embedded in remote sensing images. However, most current deep learning-based image change detection prioritize high-level semantic features, while not enough attention is given to low-level resulting loss of edges and details region. To address this problem, paper constructs a spatial-spectral cross fusion network SSCFNet, divided into three modules: feature extractor module, combined...
