摘要: The invention discloses a remote sensing data statistical property estimation algorithm based on WT (wavelet transform). includes selecting and blocking sample set for training, subjecting blocks to acquire all-order wavelet coefficients; merging the coefficients of set; according set, determining corresponding coefficient probability density distribution diagram regarding same as basis, simulating by aid GMM (Gaussian mixture model); solving model parameter an EM (expectation maximization) algorithm; verifying reasonability GMM. has advantages that large is transformed domain, are analyzed, accordingly effectively performing statistics overcoming defects prior art.
