Genetic Programming: An Introduction

Because the early Nineties, genetic programming (GP)-a self-discipline whose aim is to permit the automated new release of machine programs-has emerged as some of the most promising paradigms for quick, efficient software program improvement. GP combines organic metaphors gleaned from Darwin's conception of evolution with computer-science methods drawn from the sphere of computer studying to create courses which are in a position to adapting or recreating themselves for open-ended projects.

Development of Methods for the Characterisation of Roughness in Three Dimensions (Ultra Precision Technology Series)

In accordance with study funded by way of the eu fee, this significant guide presents a foundation for a unified method of 3-dimensional floor end evaluation. It covers a huge variety of matters concerning three-D micro-topography, with specific emphasis on standardisation, dimension, characterisation and interpretation.

Computational intelligence in image processing

Computational intelligence dependent ideas have firmly verified themselves as doable, trade, mathematical instruments for greater than a decade. they've been broadly hired in lots of platforms and alertness domain names, between those sign processing, automated keep an eye on, commercial and purchaser electronics, robotics, finance, production structures, electrical energy structures, and gear electronics.

Sample text

Notice that it is out of the scope of this chapter to define when the network reports are issued, since this will depend on how the network protocols are configured and the varying characteristics of the network itself [30]. Nevertheless, in real application scenarios, it is important to design appropriate interfacing mechanisms between the codec and the underlying network, in order that both encoder and decoder can adaptively adjust their operations according to the network conditions [12]. 9, the encoder is able to adjust the amount of intra refresh according to the network error conditions and the available bit rate.

This facilitates applications in which encoding devices are relatively cheap, small, and/or power-friendly. Some examples of these applications include wireless sensor networks, wireless video surveillance, and videoconferencing using mobile devices [44]. Many publications covering DVC have appeared (including a book on distributed source coding [DSC] [16]). The objective of this chapter is therefore to provide a comprehensive overview of the basic principles behind DVC and illustrate these principles with examples from the current state-of-the-art.

In other words, the higher the correlation between X and Y, the lower the rate can be. To construct side information Y showing strong resemblance with the original X at the encoder, the decoder should exploit as much information as possible. This could involve analyzing frames that have already been decoded, analyzing frames that are partially decoded, and/or exploiting any additional information provided by the encoder such as hash and/or lowresolution information. The available literature on side information generation is quite large.
