Optimal orthogonal boundary filter banks
نویسندگان
چکیده
The use of a paraunitary lter bank for image processing requires a special treatment at image boundaries to ensure perfect reconstruction and orthogonality of these regions. Using time-varying boundary lter banks, we will discuss a procedure that explores all degrees of freedom of the border lters in a method essentially independent of signal extensions, allowing us to design optimal boundary lter banks, while maintaining fast implementation algorithms.

Boundary filters without DC leakage for paraunitary filter banks
The construction of boundary filters without DC leakage for two-channel paraunitary FIR filter banks is considered. The design procedure is based on orthogonal boundary filters which are optimal in a weighted mean square error sense in the Fourier domain and on Householder transformation of boundary filter matrices. Simulation results are presented for boundary filters based on minimum-phase Da...
متن کاملBoundary Filters for Finite-Length Signals and Time-Varying Filter Banks
We examine the question of how to construct time-varying lter banks in the most general M-channel non-orthogonal case. We show that by associating with both analysis and synthesis operators a set of boundary lters, it is possible to make the analysis structure vary arbitrarily in time, and yet reconstruct the input with a similarly time-varying synthesis section. There is no redundancy or disto...
متن کاملOptimization design of orthogonal filter banks for image coding via multi-objective genetic algorithm
In this paper, we propose an optimisation method based on a multi-objective Genetic Algorithm (GA) for the design of orthogonal filter banks in an image coding scheme. A parameterization is used to achieve perfect reconstruction orthonormal FIR filter banks with a first order regularity. We search the optimal parameter set according to the coding gain, frequency selectivity and the group delay ...
متن کاملQuantization to maximize SNR in non-orthogonal subband coders
Recent research in the design of filter banks has shown that nonorthogonal filter banks can potentially provide higher coding gains over orthogonal filter banks. The use of non-orthogonal filter banks, however, poses a difficulty in the quantization of subband signals. The conventional nearest-neighbor (NN) encoding rule for the quantization of subband signals is no longer optimal. In this pape...
متن کاملBoundary filters with maximum coding gain and ideal DC behavior for size-limited paraunitary filter banks
This paper presents boundary optimization techniques for the processing of arbitrary-length signals with paraunitary multirate filter banks. The boundary filters are designed to maximize the coding gain while providing an ideal DC behavior. Thus, all filters except the lowpass filter are designed to have zero mean. The proposed methods give direct solutions to the problem of finding optimal bou...
