Abstract :
In this paper, we elaborate several considerations on the possible factors restricting the accuracy of covariance/coherency (C/T) matrix-based unsupervised classification. Then we make an exploration on constructing Stokes vector-based unsupervised classification. The experimental results for Fujisusono area show that Stokes vector-based method can distinguish building and farmland targets more correctly. It also shows potential to distinguish vegetations with different height or thickness.
