Optimal pansharpening of RASAT satellite imagery

2014 22nd Signal Processing and Communications Applications Conference (SIU), 2014
Pansharpening is a pixel-level fusion technique for increasing the spatial resolution of low-resolution multi-spectral satellite imagery using high resolution panchromatic imagery. In this work, the performance of various pan sharpening algorithms in improving the 7.5 meter resolution of RASAT satellite imagery is compared Nine different pansharpening ...

Pansharpening using total variation regularization [PDF]

2012 IEEE International Geoscience and Remote Sensing Symposium, 2012
In remote sensing, pansharpening refers to the technique that combines the complementary spectral and spatial resolution characteristics of a multispectral image and a panchromatic image, with the objective to generate a high-resolution color image. This paper presents a new pansharpening method based on the minimization of a variant of total variation.

Siamese Networks Based Deep Fusion Framework for Multi-Source Satellite Imagery

IEEE Access, 2022
A critical aim of pansharpening is to fuse coherent spatial and spectral features from panchromatic and multispectral images respectively. This study proposes deep siamese network based pansharpening model as a two-stage framework in a multiscale setting.

A convex formulation for hyperspectral image superresolution via subspace-based regularization

, 2014
Hyperspectral remote sensing images (HSIs) usually have high spectral resolution and low spatial resolution. Conversely, multispectral images (MSIs) usually have low spectral and high spatial resolutions. The problem of inferring images which combine the

Fine-scale mapping of vector habitats using very high resolution satellite imagery : a liver fluke case-study [PDF]

, 2014
The visualization of vector occurrence in space and time is an important aspect of studying vector-borne diseases. Detailed maps of possible vector habitats provide valuable information for the prediction of infection risk zones but are currently lacking

A Critical Comparison Among Pansharpening Algorithms

IEEE Transactions on Geoscience and Remote Sensing, 2015
Pansharpening aims at fusing a multispectral and a panchromatic image, featuring the result of the processing with the spectral resolution of the former and the spatial resolution of the latter. In the last decades, many algorithms addressing this task have been presented in the literature.
