Spectral Diversity Enhancement for Pansharpening

2018 25th IEEE International Conference on Image Processing (ICIP), 2018
Pansharpening is to generate a synthetic image with high spatial resolution and high spectral resolution via fusing panchromatic (PAN) and multispectral (MS) images. In most traditional pansharpening methods, the original MS image is firstly interpolated to the same size of PAN image by analytical interpolations.

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.
