    Abstract:

    Starting from the key problems of spectral image recognition, the improved Histogram of Oriented Gradient (Spectral Histogram of Oriented Gradient) and "Spectral total reflectance" were applied to the polarized spectral recognition study, and five dry plants and three bare soils could be recognized. In the study, the hierarchical clustering analysis was carried out by combining the length of Spectral Histogram of Oriented Gradient and Spectral total reflectance, and six study objects could be identified. Then, the length of Spectral Histogram of Oriented Gradient was used to identify the remaining two study objects by the hierarchical clustering analysis alone. As a result, the polarized spectrum of all the study objects could be recognized.
