چکیده

| Entropy-constrained vector quantization (ECVQ) 3] offers substantially improved image quality over vector quan-tization (VQ) at the cost of additional encoding complexity. We extend results in the literature for fast nearest neighbor search of VQ to ECVQ. We use a new, easily computed distance that successfully eliminates most codewords from consideration.

High Order Entropy-Constrained Residual VQ for Lossless Compression of Images

-High order entropy coding is a powerful technique for exploiting high order statistical dependencies. However, the exponentially high complexity associated with such a method often discourages its use. In this paper, an entropy-constralned residual vector quantization method is proposed for lossless compression of images. The method consists of first quantizing the input image using a high ord...

Subband Image Coding Using Entropy-Constrained Residual Vector Quantizaton

An entropy-constrained residual vector quantization design algorithm is used to design codebooks for image coding. Entropy-constrained residual vector quantization has several important advantages. It can outperform entropy-constrained vector quantization in terms of rate-distortion performance, memory, and computation requirements. It can also be used to design vector quantizers with relativel...

Conditional entropy-constrained residual VQ with application to image coding

This paper introduces an extension of entropy constrained residual vector quantization (VQ) where intervector dependencies are exploited. The method, which we call conditional entropy-constrained residual VQ, employs a high-order entropy conditioning strategy that captures local information in the neighboring vectors. When applied to coding images, the proposed method is shown to achieve better...

Vector Quantization: High-Rate Theory and Design Algorithms

The performance of opt imum vector quantizers subject to a conditional entropy constraint is studied in this paper. This new class of vector quantizers was originally suggested by Chou and Lookabaugh. A locally optimal design of this kind of vector quantizer can be accompl ished through a general ization of the well-known entropy-constrained vector quantizer (ECVQ) algorithm. This general izati...
