An IHS based Multiscale Pansharpening Technique using Wavelet based Image Fusion and Saliency Detection
With the advent of remote sensing, the requirement of high resolution images that can provide high quality spectral and spatial information has increased. Due to cost and circuitry issues, the satellite sensors are capable of providing either multispectral (MS) images with high spectral and low spatial resolution or Panchromatic (pan) images with high spatial and low spectral resolution. Pansha...
متن کاملAn Improved Variational Method for Hyperspectral Image Pansharpening with the Constraint of Spectral Difference Minimization
Variational pansharpening can enhance the spatial resolution of a hyperspectral (HS) image using a high-resolution panchromatic (PAN) image. However, this technology may lead to spectral distortion that obviously affect the accuracy of data analysis. In this article, we propose an improved variational method for HS image pansharpening with the constraint of spectral difference minimization. We ...
متن کاملHyperspectral Pansharpening Based on Intrinsic Image Decomposition and Weighted Least Squares Filter
Component substitution (CS) and multiresolution analysis (MRA) based methods have been adopted in hyperspectral pansharpening. The major contribution of this paper is a novel CS-MRA hybrid framework based on intrinsic image decomposition and weighted least squares filter. First, the panchromatic (P) image is sharpened by the Gaussian-Laplacian enhancement algorithm to enhance the spatial detail...
متن کاملImplementation of Nonlocal Pansharpening Image Fusion
This paper focuses on the implementation of the pansharpened image fusion technique proposed in the companion paper [A Nonlocal Variational Model for Pansharpening Image Fusion, SIAM Journal on Imaging Sciences, 2014, to appear]. Pansharpening refers to the process of inferring a high resolution multispectral image from a high resolution panchromatic image and low resolution multispectral one. ...
متن کاملA New Fractal Hyperspectral Image Compression Algorithm
Because of the great data of the hyperspectral image, it is not good for storage and transmission. To work out a high efficiency compression method for hyperspectral image is essential. Prediction encoding is easy to realize and has been studied widely in the hyperspectral image compression field. High compression ratio, resolution independence and fast decoding speed are the main advantages of...
