Abstract :
A new method to construct symmetric orthogonal multiwavelets (SOM) with odd harmonic property is introduced. Parameter expressions for the matrix coefficients of the multifilter banks that generate symmetric/antisymmetric scaling functions and multiwavelets supported in [0,3] are presented, its related balanced filters are constructed. Experimental results in image coding demonstrate that balanced SOM transform can perform better than the popular scalar wavelets such as Daubechiespsila biorthogonal 9/7 wavelets.
