Area-to-point regression kriging for pan-sharpening
ISPRS Journal of Photogrammetry and Remote Sensing, 2016 Pan-sharpening is a technique to combine the fine spatial resolution panchromatic (PAN) band with the coarse spatial resolution multispectral bands of the same satellite to create a fine spatial resolution multispectral image.

A Variational Approach for Pan-Sharpening
IEEE Transactions on Image Processing, 2013Pan-sharpening is a process of acquiring a high resolution multispectral (MS) image by combining a low resolution MS image with a corresponding high resolution panchromatic (PAN) image. In this paper, we propose a new variational pan-sharpening method based on three basic assumptions: 1) the gradient of PAN image could be a linear combination of those ...

Pan-sharpening using induction
2007 IEEE International Geoscience and Remote Sensing Symposium, 2007Pan-sharpening is the process of improving spatial resolution of multi-spectral (MS) satellite images using the spatial details of a high resolution panchromatic (PAN) image. Pan- sharpening can be divided into scaling and fusion processes. In the first part of this paper we use Induction instead of bicubic interpolation for up-scaling the MS images ...

Pan-sharpening via the contourlet transform
2007 IEEE International Geoscience and Remote Sensing Symposium, 2007The wavelet transform has been a popular choice for the spatial transformation in the pan-sharpening process. However, the wavelet transform do not represent the directional information efficiently. On the other hand, the contourlet transform, which also has a property of multiresolution decomposition similar to the wavelet, is known to provide ...

Fractional order variational pan-sharpening
2016 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2016In this paper, we propose a new fractional order variational method for pan-sharpening, which aims to obtain a high resolution multi-spectral (MS) image from a low resolution MS image and a high resolution panchromatic (PAN) image. On one hand, we use the data generative constraint for preserving the spectral information.

An Adaptive IHS Pan-Sharpening Method
IEEE Geoscience and Remote Sensing Letters, 2010The goal of pan-sharpening is to fuse a low spatial resolution multispectral image with a higher resolution panchromatic image to obtain an image with high spectral and spatial resolution. The Intensity-Hue-Saturation (IHS) method is a popular pan-sharpening method used for its efficiency and high spatial resolution.

Pan-sharpening based on sparse representation
2017 25th Signal Processing and Communications Applications Conference (SIU), 2017Pan-sharpening in remote sensing aims to obtain a multispectral image with high spectral and spatial information by combining spectral information of a low resolution multispectral image and spatial information of a high resolution panchromatic image. In this paper, a pan-sharpening method based on sparse representation was proposed.

Pan-sharpening: Use of difference of Gaussians
2014 IEEE Geoscience and Remote Sensing Symposium, 2014In this paper, we propose a fast method for pan-sharpening based on difference of Gaussians (DoGs). The Panchromatic (Pan) and the multi-spectral (MS) images are used to obtain a pan-sharpened image having both high spectral and spatial resolutions. The method is based on two level DoG on the Pan image.

A new variational method for pan-sharpening
2015 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2015In this paper, we present a new variational method for pan-sharpening, which aims to obtain a high resolution multi-spectral (MS) image from a low resolution MS image and a high resolution panchromatic (PAN) image. Firstly, we assume that the desired high resolution MS image after down-sampling should be close to the low resolution MS image.

On the Performance Evaluation of Pan-Sharpening Techniques
IEEE Geoscience and Remote Sensing Letters, 2007The limitations of the currently existing pan-sharpening quality indices are analyzed: the absolute difference between pixel values, mean shifting, and dynamic range change is frequently used as spatial fidelity measurement, but they may not correlate well with the actual change of image content; and spectral angle is a widely used metric for spectral ...
