OTSU Gray-level image segmentation using Otsu s method. Iseg = OTSU(I,n) computes a segmented image (Iseg) containing n classes by means of Otsu s n-thresholding method (Otsu N, A Threshold Selection Method from Gray-Level Histograms, IEEE Trans. Syst. Man Cybern. 9:62-66 1979). Thresholds are computed to maximize a separability criterion of the resultant classes in gray levels. OTSU(I) is equivalent to OTSU(I,2). By default, n=2 and the corresponding Iseg is therefore a binary image. The pixel values for Iseg are [0 1] if n=2, [0 0.5 1] if n=3, [0 0.333 0.666 1] if n=4, ... [Iseg,sep] = OTSU(I,n) returns the value (sep) of the separability criterion within the range [0 1]. Zero is obtained only with images having less than n gray level, whereas one (optimal value) is obtained only with n-valued images.

This guide is an attempt to compile a lot of that information in here and dummy it down. Perhaps it s a fairly common show, perhaps not. It might have even been a show that you taped. Whatever the case, you want to share it with others bur aren t quite sure how. This guide should be your answer. This guide is geared towards posting a show at SharingTheGroove.org. The instructions contained within are for that site. Other sites hosting BT shows may have slightly different procedures for getting the torrent to them. However, torrent creation will be the same. While this guide is being written with audio concerts in mind, the same holds true for the video section of The Groove.

he basic idea of the method of bisection is to start with an initial interval, [a0,b0], that is chosen so that f(a0)f(b0) < 0. (This guarantees that there is at least one root of the function f(x) within the initial interval.) We then iteratively bisect the interval, generating a sequence of intervals [ak,bk] that is guaranteed to converge to a solution to f(x) = 0.

Game programmers, check out the only book on data structures written especially for you! Described in layman s terms, this book will explain all of the essential data structures that are used in video game programming. It will also go over some of the more advanced and specialized data structures, too. Data Structures for Game Programmers is written in C++, and any special skills required to understand the book will be explained within it. The CD will include source code of the book, compiled demo s of the source, graphical demo code, plus tools such as Visual C++ 5, SDL, STLPort, Paint Shop Pro, and an SDL Primer by Ernest Pazera.

In engineering, compensation is planning for side effects or other unintended issues in a design. The design of an invention can itself also be to compensate for some other existing issue or exception. One example is in a voltage-controlled crystal oscillator (VCXO), which is normally affected not only by voltage, but to a lesser extent by temperature. A temperature-compensated version (a TCVCXO) is designed so that heat buildup within the enclosure of a transmitter or other such device will not alter the piezoelectric effect, thereby causing frequency drift. Another example is motion compensation on digital cameras and video cameras, which keep a picture steady and not blurry.

Short description: GUI Ant-Miner is a tool for extracting classification rules from data. It is an updated version of a data mining algorithm called Ant-Miner (Ant Colony-based Data Miner), which was proposed in 2002 by Parpinelli, Lopes and Freitas. GUI Ant-Miner differs from the original algorithm as follows: It has a friendly graphical user interface, makes possible the use of ant populations within the Ant Colony Optimization (ACO) concept, data input file is standardized with the well-known Weka system, and runs on virtually any operating system since it is written in Java.

The JavaServer Pages (JSP) Expression Language (EL) is a simple non-procedural scripting language that can be used to evaluate dynamic expressions within a JSP page. Each EL expression evaluates to a single value that is then expressed as text in the output of the JSP (when used in template text), or passed as a value to a JSP action. As such, it is ideal for adding dynamic elements to the HTML page (or other text output) generated by the execution of a JSP.
