A Research on SPOT5 Supermode Image Processing
SPOT5超模式数据处理技术研究

Supermode is a completely original technique to improve the resolution of panchromatic images,there are some paper about this technique, but few regards the issue of Supermode image processing. wewill focus on this issue in this paper. Based on a brief introduction about the supermode adopted in SPOT5satellite, the sophisticated quincunx interpolation processing is considered, which can takes advantage ofthe regularity and structure inherent in interlaced data. Further more, some researches on denoising anddeconvolution have been proposed and the main factors affect the PSF of SPOT5 imaging system areanalyzed. Finally, we take some experiments on the SPOT5 supermode images processing and somesatisfactory results are achieved.
