  Abstract

When finite length image signal is decomposed into M-band signal and synthesized using M-band orthogonal wavelet transform, the boundary signals of image are not reconstructed perfectly. For boundary signals to be reconstructed perfectly, different type filter bank or technique is applied to them when the dimension of analysed signal is the same as that of original signal. In this paper, the design method of filter bank for boundary signal is proposed. It can be designed using the singular value decomposition of boundary perfect reconstruction matrix which is obtained from paraunitary matrix. And it is also discussed to design the boundary filter bank for improving the coding performance when it is applied to subband coder. The proposed boundary filter bank shows 7% gains in PSNR compared with reflected method.
