Abstract Classification is the crux of the automatic classification of remote sensing data. Brightness of aware sort is the classification norm of distance classification. Distance classification compares brightness between aware sort and unknown pixels. Angle of spectral line is the classification norm of degree classification. Degree classification compares angle of spectral line between aware sort and unknown pixels. Using both sorts of classification, the authors classify the same remote sensing image and make a comparison between them.
