Researchers have developed RAFNet, a novel network designed to improve pansharpening by effectively fusing low-resolution multispectral and high-resolution panchromatic images. The network addresses limitations in existing deep learning methods by incorporating a Spatial Adaptive Refinement module, which uses wavelet transforms and K-means clustering to create region-specific adaptive convolution kernels. Additionally, a Clustered Frequency Aggregation module employs a sparse attention mechanism to reduce computational complexity while extracting crucial frequency features. Experiments show that RAFNet surpasses current state-of-the-art pansharpening techniques. AI
