圖像處理，利用bilt 函數(shù)
Description: This example shows how to edit (cut,paste,copy) a selection of a bitmap using BitBlt function just like Microsoft Photo Editor does. It s really EASY! take a look to the sample if you don t believe me and don t forget to VOTE FOR ME!
Note: comments are in italian...i hadn t enough time to translate them all. Sorry..(VOTE!)
As all of you know, MATLAB is a powerful engineering language. Because of some limitation, some tasks take very long time to proceed. Also MATLAB is an interpreter not a compiler. For this reason, executing a MATLAB program (m file) is time consuming. For solving this problem, Mathworks provides us C Math Library or in common language, MATLAB API. A developer can employ these APIs to solve engineering problems very fast and easy. This article is about how can use these APIs.

Welcome to EO, the Evolving Objects library.
The latest news about EO can be found on the sourceforge repository at

To get started, take a look at the tutorial, starting with
./tutorial/html/eoTutorial.html
The easiest way to start programming a new genome with all EO
evolution engines handy is to create a new standalone EO project from
the tutorial/Templates/ directory. Read Lesson 5 of the tutorial for
an introduction )
How the K-mean Cluster work
Step 1. Begin with a decision the value of k = number of clusters
Step 2. Put any initial partition that classifies the data into k clusters. You may assign the training samples randomly, or systematically as the following:
take the first k training sample as single-element clusters
Assign each of the remaining (N-k) training sample to the cluster with the nearest centroid. After each assignment, recomputed the centroid of the gaining cluster.
Step 3 . take each sample in sequence and compute its distance from the centroid of each of the clusters. If a sample is not currently in the cluster with the closest centroid, switch this sample to that cluster and update the centroid of the cluster gaining the new sample and the cluster losing the sample.
Step 4 . Repeat step 3 until convergence is achieved, that is until a pass through the training sample causes no new assignments.
DirectX not only provides fast access to the hardware and therefore incredibly speedy performance, but it also makes it much easier for hardware developers to produce new devices that work well in the Windows environment. The DirectX APIs take away the necessity of writing your own low-level, device-specific code to access hardware such as the display adapter and network card, making it much easier for you to write programs that take full advantage of the computer s multimedia capabilities.
ASP開發(fā)指南,里面的西很不錯的喲.This book is for anyone who wants to learn about using .NET for web interface design. Beginner or
hobbyist .NET developers can certainly get a good foundation of .NET web interface design by going
through this book from cover to cover. However, more seasoned .NET professionals, especially if they
tend to steer away from the GUI of their projects, can also pick up a thing or two by focusing on certain
chapters that appeal to them. This book is meant to take a reader from the beginning of a project to the
completion of the interface design. Along the way, concepts are illustrated to show how the different
pieces play together. So, anyone who really wants to understand the concepts presented in this book will
be able to do so by reading the entire thing. However, this book should also serve as a good reference
after you have read it or, in some cases, in place of reading it.
Threads are essential to Java programming, but learning to use them effectively is a nontrivial task. This new edition of the classic Java Threads shows you how to take full advantage of Java s threading facilities and brings you up-to-date with the watershed changes in Java 2 Standard Edition version 5.0 (J2SE 5.0). It provides a thorough, step-by-step approach to threads programming.
This document is intended to serve as an introduction to Wavelet processing through a set of Matlab experiments. These experiments will gives an overview of three fundamental tasks in signal and image processing : signal, denoising and compression. These scripts are selfs contents (needed additional Matlab functions can be downloaded while reading the lectures).
Each one of these five lectures should take between 1h and 2h in order to tests the various features of the scripts. One should copy/paste the provided code into a file names e.g. tp1.m, and launch the script directly from Matlab comand line > tp1 . Some of the scripts contains "holes" that you should try to fill on your own.
I also provide the complete correction of these lectures as a set of Matlab scripts, but you should try as much as possible to avoid using them.
ExcpHook is an open source (see license.txt) Exception Monitor for Windows made by Gynvael Coldwind (of Team Vexillium). t uses a ring0 driver to hook KiExceptionDispatch procedure to detect the exceptions, and then shows information about the exception on stdout (using the ring3 part of the program ofc).
The difference between this method, and the standard debug API method it that this method monitores all of XP processes, and the program does not have to attach to any other process to monitor it, hence it s harder to detect.
The code currently is considered as ALPHA, and it has been reported to BSoD sometimes (on multi core/cpu machines). take Care!
The Internet is bigger and better than what a mere browser allows. Webbots, Spiders, and Screen Scrapers is for programmers and businesspeople who want to take full advantage of the vast resources available on the Web. There s no reason to let browsers limit your online experience-especially when you can easily automate online tasks to suit your individual needs.
