A two-dimensional discrete fractional Fourier transform-based pansharpening scheme
Nidhi Saxena,Kananbala Sharma +1 more
TLDR
The proposed pansharpening scheme provides improved spectral and spatial quality as compared with the existing schemes and is robust against aliasing and mis-registration errors.Abstract:
In this paper, a new approach for fusion of multi-spectral (MS) and panchromatic (Pan) images based on 2D-discrete fractional Fourier transform (2D-DFRFT) is proposed. The proposed technique is clo...read more

Pansharpening scheme using spatial detail injection-based convolutional neural networks
TL;DR: In this article , a CNN model is used to extract the PAN detail image that is suitable for the MRA-based pansharpening scheme which significantly reduces the spatial and spectral distortions.

Pansharpening Scheme Using Bi-dimensional Empirical Mode Decomposition and Neural Network
TL;DR: In this paper , a panchromatic image was used to extract spatial detail information of the PAN image to reduce the feature values of the input and applied to the CNN to produce the nonlinear changes in the image pixels and transformed into the perfect spatial detail image.

A universal image quality index
Zhou Wang,Alan C. Bovik +1 more
TL;DR: Although the new index is mathematically defined and no human visual system model is explicitly employed, experiments on various image distortion types indicate that it performs significantly better than the widely used distortion metric mean squared error.

Empirical study of particle swarm optimization
Yuhui Shi,Russell C. Eberhart +1 more
TL;DR: The experimental results show that the PSO is a promising optimization method and a new approach is suggested to improve PSO's performance near the optima, such as using an adaptive inertia weight.

Comparison of three different methods to merge multiresolution and multispectral data: Landsat TM and SPOT panchromatic
TL;DR: In this paper, the results of three different methods used to merge the information contents of the Landsat Thermatic Mapper (TM) and Satellite Pour l'Observation de la Terre (SPOT) panchromatic data are compared.

Multiresolution-based image fusion with additive wavelet decomposition
TL;DR: The authors developed a technique, based on multiresolution wavelet decomposition, for the merging and data fusion of high-resolution panchromatic and multispectral images which is clearly better than the IHS and LHS mergers in preserving both spectral and spatial information.
