Dead Zone Quantization in Wavelet Image Compression | Mini Project in Ece 253a |
A common quantizer implementation of wavelet image compression systems is scalar quantization followed by run-length and Hu man coding. The low complexity of such a quantizer system makes it suitable for hardware implementations. By replacing the scalar quantizer with a dead zone quantizer, the performance of the system in terms of PSNR/bpp increases. The purpose of this mini project is to inve...
متن کاملSpace-frequency quantization for wavelet image coding
A new class of image coding algorithms coupling standard scalar quantization of frequency coefficients with tree-structured quantization (related to spatial structures) has attracted wide attention because its good performance appears to confirm the promised efficiencies of hierarchical representation. This paper addresses the problem of how spatial quantization modes and standard scalar quanti...
متن کاملModulus quantization for matching-pursuit video coding
Overcomplete signal decomposition using matching pursuits has been shown to be an eecient technique for coding motion residual images in a hybrid video coder. Unlike orthogonal decomposition, matching pursuit uses an in-the-loop modulus quantizer which must be speciied before coding begins. This complicates the quantizer design, since the optimal quantizer depends on the statistics of the match...
متن کاملLow Bit Rate Color Image Coding with Adaptive Encoding of Wavelet Co-efficients
Current trends in image coding exploit the advantage of subband / wavelet decompositions in reducing the complexity in optimal scalar / vector quantizer (SQ / VQ) design. Compression ratios of the order of 10: 1 to 20: 1 with high visual quality has been achieved by using vector quantization of subband decomposed color images in peceptually weighted color spaces. We report the performance of th...
متن کاملQuantization as Histogram Segmentation: Globally Optimal Scalar Quantizer Design in Network System
We propose a polynomial-time algorithm for optimal scalar quantizer design on discrete-alphabet sources. Special cases of the proposed approach yield optimal design algorithms for fixed-rate and entropy-constrained scalar quantizers, multi-resolution scalar quantizers, multiple description scalar quantizers, and Wyner-Ziv scalar quantizers. The algorithm guarantees globally optimal solutions fo...
