Pansharpening Based on Joint-Guided Detail Extraction

Abstract: Pansharpening is the process of fusing low spatial resolution multispectral (MS) images with high spatial resolution panchromatic (PAN) images, so as to obtain high spatial resolution multispectral (HRMS) images. In this study, a new pansharpening method based on a joint-guided detail extraction is proposed to maintain the spectral and spatial fidelity of a pansharpened image. First, to obtain details that are highly correlated with an MS image, a new PAN image is constructed and guided by the intensity compon… Show more

“…With the improvements of hardware and convolutional neural networks (CNN) in image processing applications, deep learning (DL)-based methods represent the emerging methods of image processing [36][37][38][39][40][41][42][43][44][45][46][47][48][49]. Denoising methods [36,37] for modeling HSIs by 2D convolutions are effective, but sacrifice the ability of the model to extract GCS knowledge and flexibility with spectral dimensions.…”

“…A method based on a joint-guided detail extraction can reduce spectral and spatial distortion with a little computational burden. Here, variational model is designed to obtain a new PAN image guided by the MS image and improve the correlation [31].…”

“…In recent years, CS-and MRA-based methods have generally been defined and realized by injection models. In particular, the CS-based injection model is used extensively owing to its high spatial quality and efficiency [30]. However, it is difficult to obtain satisfactory spectral quality with this model [28].…”

“…However, two deficiencies remain that may affect the fusion quality. The first is that the low correlation between the PAN and MS images may cause spectral distortion [30]. The second is that vegetated and non-vegetated regions are rarely differentiated when determining the injection gains, which will cause spatial and spectral distortion [33].…”
