Study of uncertainties of hyperspectral image based on Fourier waveform analysis

Satellite-based spectra are a complicated function of imaging time, imaging azimuth, imaging channel, atmospheric status and ground object category. This complicated function accordingly leads to the ambiguity and uncertainty of satellite-based spectra and image classification. The uncertainty of satellite-based spectra can be divided into two categories. One is background noise; the other is SODS (same object different spectrum) and DOSS (different object similar spectrum). A method to analyze and lower the DOSS uncertainty of satellite-based spectra based on Fourier waveform analysis is discussed in this paper
