Minimum Mean Square Error Fir Filter Banks with Arbitrary Filter Lengths
The performance of subband image coders depends on the proper choice of filter banks. It is therefore desirable to find algorithms for optimizing the filter banks. A theory for finding jointly optimized analysis and synthesis filter banks with arbitrary filter lengths and arbitrary delay through the filter bank is proposed. Theoretical results are included. Comparisons are made against the well known 5/3, 9/7, and 10/18 wavelets. The proposed filter banks, which are both rate and source dependent, have a better distortion rate performance for all cases.
