// // Histogram Sample // This sample shows how to use the Sample Grabber filter for video image processing. // Conceptual background: // A histogram is just a frequency count of every pixel value in the image. // There are various well-known mathematical operations that you can perform on an image // using histograms, to enhance the image, etc. // Histogram stretch (aka automatic gain control): // Stretches the image histogram to fill the entire range of values. This is a "point operation," // meaning each pixel is scaled to a new value, without examining the neighboring pixels. The // histogram stretch does not actually require you to calculate the full histogram. The scaling factor // is calculated from the minimum and maximum values in the image.

本實訓(xùn)是有關(guān)線性表的順序存儲結(jié)構(gòu)的應(yīng)用，在本實訓(xùn)的實例程序中，通過C語言中提供的數(shù)組來存儲兩個已知的線性表，然后利用數(shù)組元素的下標來對線性表進行比較。通過對本實訓(xùn)的學(xué)習(xí)，可以理解線性表在順序存儲結(jié)構(gòu)下的操作方法。 在實訓(xùn)中，我們設(shè)A=（a1,a2,…,an）和B=（b1,b2,…,bm）是兩個線性表，其數(shù)據(jù)元素的類型是整型。若n=m,且ai=bi,則稱A=B 若ai=bi，而aj<bj,則稱A<B；除此以外，均稱A>B。設(shè)計一比較大小的程序。

Jvm 規(guī)范說明。The Java Virtual Machine was designed to support the Java programming language. Some concepts and vocabulary from the Java language are thus necessary to understand the virtual machine. This chapter gives enough of an overview of Java to support the discussion of the Java Virtual Machine to follow. Its material has been condensed from The Java Language Specification, by James Gosling, Bill Joy, and Guy Steele. For a complete discussion of the Java language, or for details and examples of the material in this chapter, refer to that book. Readers familiar with that book may wish to skip this chapter. Readers familiar with Java, but not with The Java Language Specification, should at least skim this chapter for the terminology it introduces.

What I am trying to introduce here is a full fledged Java Instant messenger, which has all the features supplied by commercial messengers like Yahoo or MSN. Although it cannot compared to be in par with those messengers, it is an attempt by me to learn Advanced Java and JNI concepts. The challenges I faced here were often overcome by referring to numerous sites, which nearly zeroes in or completely solved the issues I faced at that point of time. It improved my learning curve and also believe would do the same to you too. Ofcourse, there are some bugs and glitches, which I hope you would excuse. Thanks to anyone who takes the pain to report them or even suggest better way of doing things to me.

Use the fast Fourier transform function fft to analyse following signal. Plot the original signal, and the magnitude of its spectrum linearly and logarithmically. Apply Hamming window to reduce the leakage. . The hamming window can be coded in Matlab as for n=1:N hamming(n)=0.54+0.46*cos((2*n-N+1)*pi/N); end; where N is the data length in the FFT.

At present, there is a strong worldwide push toward bringing fiber closer to indi- vidual homes and businesses. Fiber-to-the-Home/Business (FTTH/B) or close to it networks are poised to become the next major success story for optical fiber com- munications. In fact, FTTH connections are currently experiencing double-digit or even higher growth rates, e.g., in the United States the annual growth rate was 112% between September 2006 and September 2007, and their presence can add value of U.S. $4,000–15,000 to the selling price of a home.

RFID networks are currently recognized as one a research area of priority. Research activities related to RFID technology have been booming recently. A number of ongoing projects are being funded in Europe, Asia, and North America. According to leading market analysts, the development of the RFID market is projected to increase from approximately $3 billion in 2005 to $25 billion in 2015. Several countries have dedicated innovation programs to support and develop RFID systems and related technologies: the RFID initiative in Taiwan, Ubiquitous Japan and the NSF SBIR program in the USA. The EU has recently advertised its Strategic Research Roadmap concerning the Internet of Things, which first of all refers to the RFID technology before being extended to commu- nicating devices as in M2M (Machine to Machine). In this roadmap, several application domains have been identified:
