Research effort has recently focused on designing feature weighting clustering algorithms. These algorithms automatically calculate the weight of each feature, representing their degree of relevance, in a data set. However, since most of these evaluate one feature at a time they may have difficulties to cluster data sets containing features with similar information. If a group of features conta...

This chapter discusses the problem of coding images using very redundant libraries of waveforms, also referred to as dictionaries. We start with a discussion of the shortcomings of classical approaches based on orthonormal bases. More specifically, we show why these redundant dictionaries provide an interesting alternative for image representation. We then introduce a special dictionary of 2-D ...

Using gray-scale texture features recently becomes a new trend in supervised machine learning crater detection algorithms. To provide better classification of craters in planetary images, feature subset selection is used to reduce irrelevant and redundant features. Feature selection is known to be NPhard. To provide an efficient suboptimal solution, three genetic algorithms are proposed to use ...

A novel method that can be used to evaluate mura grade on Flat Panel Displays (FPD) has been developed. This method is capable of evaluating the edge gradients of the mura. This is accomplished by converting the mura image into a visual sensitivity image using a contrast sensitivity function filter. It was determined that the sum of the visual sensitivity values of the mura regions correlated s...

Abstract: A Mura (also called “alluck”) defect that causes local deterioration of colors or brightness on a LCD(liquid crystal display) panel is one of the critical issues in display manufacturing. In this paper, we propose mura detection method using frequency filtering. As a mean of frequency filtering to eliminate the low frequency background term, subtraction of the averaged image from the ...

A fast parallel arithmetic using a Cellular Automaton (CA) environment is presented. Th e Redundant Binary (RB) number representation, first studied for optical computing , is used in order to perform a carry-free parallel addition or algebraic sum of arbitrary large numbers in constant time.

Most work in game theory is conducted under the assumption that the players are expected utility maximizers. Expected utility is a very tractable decision model, but is prone to wellknown paradoxes and empirical violations (Allais 1953, Ellsberg 1961), which may induce biases in game-theoretic predictions. La Mura (2009) introduced a projective generalization of expected utility (PEU) which avo...
