Pansharpening techniques aim at fusing a low-spatial resolution multispectral (MS) image with a higher spatial resolution panchromatic (PAN) image to produce an MS image at high spatial resolution. Despite significant progress in the field, spectral and spatial distortions might still compromise the quality of the results. We introduce a restoration strategy to mitigate artifacts of fused products. After applying the principal component analysis transform to a pansharpened image, the chromatic components are filtered conditionally to the geometry of PAN. The structural component is then replaced by the locally histogram-matched PAN for spatial enhancement. Experimental results illustrate the efficiency of the proposed restoration chain.

The recent development, achieved on SC devices for grid applications, requires the support of design tools in order to establish the impact of these new devices on the operation of the electrical system. Classically, standard simulation programs are used in grid design and maintenance by the utilities; but these new devices require user written models, compatible with the grid simulators. In this paper, a user written model for the integration of superconducting cables in the grid, with the capacity to simulate dynamic behavior, is presented. Results of the simulations are presented which refer to the overall grid performance. [ABSTRACT FROM AUTHOR]
