Abstract :
In this paper, a technique for spectral pixel reconstruction is proposed by combining information from multiple spectral bands of the same scene acquired by a satellite. By "spectral-pixel super-resolution", we mean recovering an unavailable spectral band, suitable for different band combinations for a variety of applications. The technique includes radiometric registration, modulation transfer correction followed by noise reduction. We also compare the results of reconstruction quantitatively and qualitatively.
