In this paper, the average level crossing rate of the ratio of product of two k-µ random variables and k-µ random variable will be analyzed. The joint probability density function of the ratio of product of two k-µ random variables and k-µ random variable and its first derivative will be calculated. By using this expression, the average level crossing rate(More)
Transform coding is commonly used in image processing algorithms to provide high compression ratios, often at the expense of processing time and simplicity of the system. We have recently proposed a pixel value prediction scheme in order to exploit adjacent pixel correlation, providing a low-complexity model for image coding. However, the proposed model was(More)
In this paper both piecewise linear and piecewise uniform approximation of probability density function are performed. For th e probability density function approximated in these ways, a compressor function is formed. On the basis of compressor function formed in this way, piecewise linear and piecewise uniform companding quantizer are designed. Design of(More)
