First, according to the expression of orthogonal symmetry 2D wavelets and its regularity codition,we construct a high-order multivariable polynomial system. This system is decomposed two subsystems,by application Groebner bases algorithm, all coefficients of 2-3 order regular wavelets filters banks are obtained. So we have constructed the best 2D wavelets which is orthogonal, symmetric and high-regular. Second 2D wavelets decomposed-reconstructed algorithm is derived by 2D orthogonal multiresolution analysis. At last a based on 3-order regular 2D wavelets SPIHT coding algorithm is used to remote sensing image coding. Experimental results show that it is much better coding performance.
