Quality analysis of pansharpened images

IEEE International IEEE International IEEE International Geoscience and Remote Sensing Symposium, 2004. IGARSS '04. Proceedings. 2004, 2004
In general, image fusion or sharpening is of great importance to various remote sensing and mapping applications, where the spatial information from a "high-resolution" image is merged with the radiometric information from a "low-resolution" image.

Affinity Pansharpening and Image Fusion

2014 International Conference on Digital Image Computing: Techniques and Applications (DICTA), 2014
A novel framework for enhancing the resolution of a low-resolution multispectral or hyperspectral image using a high resolution panchromatic image or multispectral image is proposed in this paper. This framework can be further used to perform more general types of image fusion.

Pansharpening and image quality interface

IEEE International IEEE International IEEE International Geoscience and Remote Sensing Symposium, 2004. IGARSS '04. Proceedings. 2004, 2004
Pansharpening techniques increase the spatial resolution of multispectral images and also simultaneously preserve the spectral information in the multispectral data. Pansharpening is also expressed as resolution merge, image integration, and multisensor data fusion.

Pansharpening Based on Semiblind Deconvolution

IEEE Transactions on Geoscience and Remote Sensing, 2015
Many powerful pansharpening approaches exploit the functional relation between the fusion of PANchromatic (PAN) and MultiSpectral (MS) images. To this purpose, the modulation transfer function of the MS sensor is typically used, being easily approximated as a Gaussian filter whose analytic expression is fully specified by the sensor gain at the Nyquist

Pansharpening

Pansharpening is the process of using a high-resolution panchromatic image to enhance the spatial resolution of a multispectral image acquired over the same area. This technique allows high-quality multispectral images to be obtained, while significantly reducing the requirements placed on both the onboard imaging systems and the resources needed for ...

High-Quality Bayesian Pansharpening

IEEE Transactions on Image Processing, 2019
Pansharpening is a process of acquiring a multi-spectral image with high spatial resolution by fusing a low resolution multi-spectral image with a corresponding high resolution panchromatic image. In this paper, a new pansharpening method based on the Bayesian theory is proposed.

Universal Pansharpening Model

Pansharpening generates the high-resolution multi-spectral (MS) image by integrating spatial details from a texture-rich panchromatic (PAN) image and spectral attributes from a low-resolution MS image. Existing methods are predominantly satellite-specific and scene-dependent, which severely limits their generalization across heterogeneous sensors and ...

Better Image Filter for Pansharpening

IEEE Transactions on Image Processing
The modulation transfer function tailored image filter (MTF-TIF) has long been regarded as the optimal filter for multispectral image pansharpening. It excels at simulating the camera's frequency response, thereby capturing finer image details and significantly improving pansharpening performance.

Model-Based Reduced-Rank Pansharpening

IEEE Geoscience and Remote Sensing Letters, 2020
Observation of the Earth using satellites mounted with optical sensors is an important application of remote sensing. Owing to physical constraints, multispectral (MS) sensors acquire images of lower spatial resolution than a single-band panchromatic (PAN) sensor that acquires images of the same scene.

Pansharpening based on an improved ratio enhancement

2015 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2015
Pansharpening technique is very important for many remote sensing applications. Many fusion algorithms have been proposed to pan-sharpen multispectral (MS) images. However, there are still some spatial or spectral distortion problems in fusion result.
