QNR Optimization based Pansharpening [PDF]

open access: yesIGARSS 2008 - 2008 IEEE International Geoscience and Remote Sensing Symposium, 2008
Quality Without Reference (QNR) index can be used to globally assess the quality of pansharpened images without the need of a reference high resolution multispectral (MS) image. The QNR index relies on local calculation of the Q4 index. Exploiting the local Q4 calculation property of the QNR index, we propose an injection model for pansharpening.

Multispectral Pansharpening Based on Multisequence Convolutional Recurrent Neural Network

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2022
Multispectral (MS) pansharpening is defined as the fusion of spatial information in panchromatic (PAN) image and spectral information in MS image. In this work, we propose an MS pansharpening based on multisequence convolutional recurrent neural network (

AESGGAN: an attention embedded adversarial network for pansharpening

open access: yes四川大学学报. 自然科学版, 2023
Pansharpening aims to fuse low-resolution multispectral image with high-resolution panchromatic image to generate a high-resolution multispectral image. With the development of Convolutional Neural Network (CNN), many CNN-based pansharpening methods have

An Unsupervised CNN-Based Hyperspectral Pansharpening Method

open access: yes, 2023
This work proposes a simple yet effective method to adapt unsupervised convolutional neural networks for pansharpening of multispectral images to the problem of hyperspectral image pansharpening, i.e., the fusion of a single high-resolution panchromatic ...

Pansharpening by Combining Enhanced Spatial-Spectral Fidelity and Gradient-Domain Guided Filtering

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2023
Pansharpening techniques fuse the complementary information from a high-resolution panchromatic (PAN) and low-resolution multispectral (LRMS) images to produce a high-resolution multispectral (HRMS) image.

Full-Resolution Quality Assessment for Pansharpening

open access: yesRemote Sensing, 2022
A reliable quality assessment procedure for pansharpening methods is of critical importance for the development of the related solutions. Unfortunately, the lack of ground truths to be used as guidance for an objective evaluation has pushed the community to resort to two approaches, which can also be jointly applied.

Quality assessment by region in spot images fused by means dual-tree complex wavelet transform [PDF]

open access: yes, 2011
This work is motivated in providing and evaluating a fusion algorithm of remotely sensed images, i.e. the fusion of a high spatial resolution panchromatic image with a multi-spectral image (also known as pansharpening) using the dual-tree complex wavelet

Pansharpening Using Guided Filtering to Improve the Spatial Clarity of VHR Satellite Imagery

open access: yesRemote Sensing, 2019
Pansharpening algorithms are designed to enhance the spatial resolution of multispectral images using panchromatic images with high spatial resolutions. Panchromatic and multispectral images acquired from very high resolution (VHR) satellite sensors used

A Local and Nonlocal Feature Interaction Network for Pansharpening

open access: yesRemote Sensing, 2022
Pansharpening based on deep learning (DL) has shown great advantages. Most convolutional neural network (CNN)-based methods focus on obtaining local features from multispectral (MS) and panchromatic (PAN) images, but ignore the nonlocal dependence on ...
