Convolutional Sparse Representation of Injected Details for Pansharpening
IEEE Geoscience and Remote Sensing Letters(2019)
摘要
In this letter, we address the pansharpening problem, which focuses on constructing a high-resolution (HR) multispectral (MS) image from a low-resolution (LR) MS and an HR panchromatic (Pan) image. The accuracy of pansharpening method based on sparse representation (SR) mainly depends on the construction of dictionary and the learning of sparse coefficients, while the details injection (DI)-based ...
