Wavelets, Approximation and Compression: A Review
In this paper, we briefly review the connection between subband coding, wavelet approximation and general cornpression problems. Wavelet or subband coding is successful in compression applications partly because of the good approximation properties of wavelets. First, we revisit some rate-distortion bounds for wavelet approximation of piecewise smooth functions. We contrast these results with r...
متن کاملA Signal-Specific QMF Bank Design Technique Using Karhunen-Loéve Transform Approximation
Block Wavelet Transforms (BWTs) are orthogonal matrix transforms that can be obtained from orthogonal subband filter banks. They were initially generated to produce matrix transforms which may carry nice properties inheriting from wavelets, as alternatives to DCT and similar matrix transforms. Although the construction methodology of BWT is clear, the reverse operation was not researched. In ce...
متن کاملConstrained Optimization Offilter Banks in Subband
The design of lter banks in subband image coding is critical for achieving high image quality. In this paper, we study the design from both the signal processing domain and the theory of wavelets. We formulate the design of lter banks as a two-stage nonlinear constrained optimization problem, each of which is solved by sequential quadratic programming (SQP). Using a wavelet image coding prototy...
متن کاملBiorthogonal Bases of Compactly Supported Wavelets
Orthonormal bases of compactly supported wavelet bases correspond to subband coding schemes with exact reconstruction in which the analysis and synthesis filters coincide. We show here that under fairly general conditions, exact reconstruction schemes with synthesis filters different from the analysis filters give rise: to two dual Riesz bases of compactly supported wavelets. We give necessary ...
متن کاملA tutorial overview of filter banks, wavelets and interrelations
Two channel lter banks (FBs) were developed for subbandspeech coding [16]. Since then FB theory has grown to includeFBs with more than two channels, tree-structured FBs etc. Arich theory for the design and implementation of FBs exists.Wavelets were originally developed as an alternative to theSTFT for non-stationary signal analysis [26]. Since then it hasbeen realized th...
