FSGformer: Frequency Separation and Guidance Transformer for Pansharpening
Pansharpening is a crucial task in remote sensing image processing, aiming to generate high-resolution multispectral (HRMS) images by fusing low-resolution multispectral (LRMS) images with high-resolution panchromatic (PAN) images. However, most current deep learning methods for pansharpening rarely consider the frequency differences in PAN and MS images effectively, resulting in harmful mixing of...Show More

Kaiyu Li;Xiangyong Cao;Yupeng Deng;Jiayi Song;Junmin Liu;Deyu Meng;Zhi Wang
Change detection (CD) aims to identify pixels with semantic changes between images. However, annotating massive numbers of pixel-level images is labor-intensive and costly, especially for multitemporal images, which require pixel-wise comparisons by human experts. Considering the excellent performance of visual-language models (VLMs) for zero-shot, OV, etc., with prompt-based reasoning, it is prom...Show More
