Аннотация

In this paper high dynamic range no uniform two-dimensional vector quantization model for Laplace an source was provided. Semi logarithmic A-law compression characteristic was used as radial scalar compression characteristic of two-dimensional vector quantization. Optimal number value of concentric quantization domains (amplitude levels) is expressed in the function of parameter A. Exact distortion analysis with obtained closed form expressions is provided. It has been shown that proposed model provides high signal-to-quantization noise Ratio (SQNR) values in wide range of variances, and over Achieves quality obtained by scalar A-law quantization at the same bit rate, so it can be used in various switching and adaptation implementations for realization of high quality signal compression.
