Description: There are many approaches for motion detection in continuous video streams. All of them are based on comparison of current video frame with one from the previous frames or with something that we ll call background. In this article I ll try to describe some of the most common approaches. In describing the algorithms, I ll use an image processing library I ve described in my previous article. So, if you are common with it, it will only help. The demo applications support the following types of video sources: AVI files (using Video for Windows, interop library is included) updating JPEG from internet cameras MJPEG (motion JPEG) streams from different internet cameras MMS Stream - Microsoft Media Services local capture device (USB cameras or other capture devices).-There are many approaches for motion detection in continuous video streams.

Description: Quite often, you want to customize the colors shown in your dialogs. Maybe a unique, original look is required (and you don t want to go all the way into skinning) perhaps a red background seems suitable for critical error messages if you ve developed a complex dialog, parts of which serve as drop targets, you might want to emphasize those: or, in a form with required fields, you might want a different color for them. -Quite often, you want to customize the colors shown in your dialogs.

Description: mad mp3解码dll
libmad is a powerful open source library written in C that decodes MP3 files to uncompressed PCM data. However, it compiles as a static library, limiting its access to C/C++. I have written code (based on the source madlld) that compiles to a DLL, enabling other languages (i.e., C#, Visual Basic etc.) to access the libmad library using the simple interface I ve provided.

Description: Basically, this article describes one way to implement the 1D version of the FFT algorithm for an array of complex samples. The intention of this article is to show an efficient and fast FFT algorithm that can easily be modified according to the needs of the user. I ve studied the FFT algorithm when I was developing a software to make frequency analysis on a sample of captured sound.-Basically, this article describes one way to implement the 1D version of the FFT algorithm for an array of co mplex samples.

Description: A group of programmers far smarter than I have been laboring from some time to create a library of utilities to help developers like myself to create better applications. The fruits of that labor is the Enterprise Library from the Patterns & Practices group at Microsoft. The Enterprise Library encompasses Exception Handling, Logging, Caching, Security, Cryptography, and Database Access. The latest incarnation of the Enterprise Library for the .Net 2.0 framework also includes an ObjectBuilder which allows object creation with dependency injection. I’d be lying to you if I told you I understand exactly what the ObjectBuilder does. Brian Button has released the most complete information I have found so far on the ObjectBuilder. Documentation is scarce at this point since the Enterprise Library has not been officially released. The code covered in this article is based on the December Community Technology Preview of the new Enterprise Library.-A group of programmers far smarter than I ha ve been laboring from some time to create a libra ry of utilities to help developers like myself t o create better applications.

Description: This example program shows how to configure and use the A/D Converter of the following microcontroller:
STMicroelectronics ST10F166
After configuring the A/D, the program reads the A/D result and outputs the converted value using the serial port.
To run this program...
Build the project (Project Menu, Build Target)
Start the debugger (Debug Menu, Start/Stop Debug Session)
View the Serial Window (View Menu, Serial Window #1)
View the A/D converter peripheral (Peripheral Menu, A/D Converter)
Run the program (Debug Menu, Go)
A debug script (debug.ini) creates buttons that set different analog values in A/D channels. As the program runs, you will see the A/D input and output change.
Other buttons create signals that generate sine wave or sawtooth patterns as analog inputs. µ Vision3 users may enable the built-in Logic Analyzer to view, measure and compare these input signals graphically.-This example shows how to program configur e and use the A/D Converter of the following MICR ocontroller : STMicroelectronics ST10F166 After configuri ng the A/D, the program reads the A/D and outputs the result converted value using the serial port.

Description: In this book, we aim to give you an introduction to a wide variety of topics important to you as a developer using UNIX. The word Beginning in the title refers more to the content than to your skill level. We ve structured the book to help you learn more about what UNIX has to offer, however much experience you have already. UNIX programming is a large field and we aim to cover enough about a wide range of topics to give you a good beginning in each subject.

Description: MFC Black Book
Introduction:
Are you an MFC programmer? Good. There are two types of MFC programmers. What kind are you? The first kind are the good programmers who write programs that conform to the way MFC wants you to do things. The second bunch are wild-eyed anarchists who insist on getting things done their way. Me, I’m in the second group. If you are in the same boat (or would like to be) this book is for you.
This book won’t teach you MFC—not in the traditional sense. You should pick it up with a good understanding of basic MFC programming and a desire to do things differently. This isn’t a Scribble tutorial (although I will review some fundamentals in the first chapter). You will learn how to wring every drop from your MFC programs. You’ll discover how to use, abuse, and abandon the document/view architecture. If you’ve ever wanted custom archives, you’ll find that, too.-MFC Black Book Introduction : Are you an MFC programmer Good. There are two typ es of MFC programmers.
