Since pre-filter is more likely to cause the orthogonality and symmetry "losses" of multi wavelet

and to cause the increase of the compact support of the base function

a multiwavelet "balanced" algorithm is proposed to make multiwavelets have the same properties with single wavelets.Taking full advantages of the structures of balanced multiwavelet decomposition coefficients

the Embedded Block Coding with Optimal Truncation(EBCOT) image coding algorithm is used to compress the coefficients of balanced multiwavelet. When the compressed ratio reaches 32

the PSNR is 31.342 7. The experimental results show that the balanced multiwavelet algorithm based on EBCOT has many good characteristics

such as orthogonality

short support

high vanishing moments

etc.

which is a more effective method for aviation image compression.
