Adaptive Polyphase Subband Decomposition Structures for Image Compression
Subband decomposition techniques have been extensively used for data coding and analysis. In most lter banks, the goal is to obtain subsampled signals corresponding to di erent spectral bands of the original data. However, this approach leads to various artifacts in images containing text, subtitles, or sharp edges. In this paper, adaptive lter banks with perfect reconstruction property are pre...
متن کاملLinear/nonlinear adaptive polyphase subband decomposition structures for image compression
Subband decomposition techniques have been extensively used for data coding and analysis. In most filter banks, the goal is to obtain subsampled signals corresponding to different spectral regions of the original data. However, this approach leads to various artifacts in images having spatially varying characteristics, such as images containing text, subtitles, or sharp edges. In this paper, ad...
متن کاملNew Subband Adaptive IIR Filter Based On Polyphase Decomposition
Abstract—We present a subband adaptive infinite-impulse response (IIR) filtering method, which is based on a polyphase decomposition of IIR filter. Motivated by the fact that the polyphase structure has benefits in terms of convergence rate and stability, we introduce the polyphase decomposition to subband IIR filtering, i.e., in each subband high order IIR filter is decomposed into polyphase I...
متن کاملImage denoising using adaptive subband decomposition
In this paper, we present a new image denoising method based on adaptive subband decomposition (or adaptive wavelet transform) in which the filter coefficients are updated according to an Least Mean Square (LMS) type algorithm. Adaptive subband decomposition filter banks have the perfect reconstruction property. Since the adaptive filterbank adjusts itself to the changing input environments den...
متن کاملPolyphase IIR filter banks for subband adaptive echo cancellation applications
Polyphase IIR structures are known to be very attractive for very high performance filters that can be designed using very few coefficients. This combined with their reduced sensitivity to coefficient quantization in comparison to standard FIR and IIR structures makes them very applicable to very fast filtering especially when implemented in fixed point arithmetic. In this paper we suggest repl...
