Cross Residual Fusion for Pansharpening

2021 IEEE International Geoscience and Remote Sensing Symposium IGARSS, 2021
In this work, a deep learning approach has been developed to carry out optical remote sensing pansharpening by the fusion of high spectral and spatial information from two different sources. In the proposed approach, the combination of multimodal information is achieved at multiple levels.

Pansharpening of Mastcam images

2017 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2017
This paper summarizes a new investigation of applying advanced pansharpening algorithms to enhance the images of the left imager in the Mastcam onboard the Curiosity rover, which landed on Mars in 2012. The various instruments on the rover have already made great contributions in the understanding of Mars.

Pansharpening With Matting Model

IEEE Transactions on Geoscience and Remote Sensing, 2014
Pansharpening aims at creating a fused image of high spatial and spectral resolutions through merging a panchromatic (PAN) image with a multispectral (MS) image. Component substitution is the most widely used pansharpening method. However, most research in this field focuses on improving the existing component substitution-based pansharpening methods ...

Hyperspectral Pansharpening With Guided Filter

IEEE Geoscience and Remote Sensing Letters, 2017
A new hyperspectral (HS) pansharpening method based on guided filter is proposed in this letter. The proposed method, which obtains the spatial detail difference of each band successively, is different from the traditional component substitution method. The detail information of each band is extracted at first.

Hyperspectral Pansharpening With Deep Priors

IEEE Transactions on Neural Networks and Learning Systems, 2020
Hyperspectral (HS) image can describe subtle differences in the spectral signatures of materials, but it has low spatial resolution limited by the existing technical and budget constraints. In this paper, we propose a promising HS pansharpening method with deep priors (HPDP) to fuse a low-resolution (LR) HS image with a high-resolution (HR ...

Spectral Diversity Enhancement for Pansharpening

2018 25th IEEE International Conference on Image Processing (ICIP), 2018
Pansharpening is to generate a synthetic image with high spatial resolution and high spectral resolution via fusing panchromatic (PAN) and multispectral (MS) images. In most traditional pansharpening methods, the original MS image is firstly interpolated to the same size of PAN image by analytical interpolations.

Quality analysis of pansharpened images

IEEE International IEEE International IEEE International Geoscience and Remote Sensing Symposium, 2004. IGARSS '04. Proceedings. 2004, 2004
In general, image fusion or sharpening is of great importance to various remote sensing and mapping applications, where the spatial information from a "high-resolution" image is merged with the radiometric information from a "low-resolution" image.

Affinity Pansharpening and Image Fusion

2014 International Conference on Digital Image Computing: Techniques and Applications (DICTA), 2014
A novel framework for enhancing the resolution of a low-resolution multispectral or hyperspectral image using a high resolution panchromatic image or multispectral image is proposed in this paper. This framework can be further used to perform more general types of image fusion.

Pansharpening and image quality interface

IEEE International IEEE International IEEE International Geoscience and Remote Sensing Symposium, 2004. IGARSS '04. Proceedings. 2004, 2004
Pansharpening techniques increase the spatial resolution of multispectral images and also simultaneously preserve the spectral information in the multispectral data. Pansharpening is also expressed as resolution merge, image integration, and multisensor data fusion.

Pansharpening Based on Semiblind Deconvolution

IEEE Transactions on Geoscience and Remote Sensing, 2015
Many powerful pansharpening approaches exploit the functional relation between the fusion of PANchromatic (PAN) and MultiSpectral (MS) images. To this purpose, the modulation transfer function of the MS sensor is typically used, being easily approximated as a Gaussian filter whose analytic expression is fully specified by the sensor gain at the Nyquist
