Relatively low spatial resolution of the space-borne hyper-spectral images (HSI) is the main drawback to derive value added products. Recently, several techniques have been proposed in order to enhance the spatial resolution HSI by means of fusion with higher spatial resolution multispectral images. This paper presents an alternative approach based on the joint sparsity model for spectral unmixing...
The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) has acquired more than 1 million data with along-track stereovision. These data are processed to make digital elevation model (DEM) with orthorectified images. Using multiple DEMs obtained at different times, it is expected to enhance the spatial resolution. In this work, the methodology to enhance the resolution of DEM, especially...
