style='font-family:宋体;"Times New Roman"'>。但是要知道：万丈高楼平地起，很多非常复杂的功能可能是一些简单方法的叠加。相信你自己吧，你一定能够成为图象处理大师的。</span></p>

<p style='line-height:18.0pt'><span
style='font-family:宋体;"Times New Roman"'>有人会问：“在编这样的程序之前有什么要求吗？”回答是：“有，只有两条：</span><span lang=EN-US>(1)</span><span

lang=EN-US>(1)<span style='font:7.0pt "Times New Roman"'> </span></span>
<span
style='font-family:宋体;"Times New Roman"'>文中出现的所有例子都在我自己的机器上编译运行通过，我使用的编程语言为</span><span lang=EN-US>Visual
C++4.1</span><span style='font-family:宋体;
"Times New Roman"'>，运行环境为中文</span><span lang=EN-US>Windows95</span><span
style='font-family:宋体;"Times New Roman"'>或</span><span lang=EN-US>Windows98</span><span
style='font-family:宋体;"Times New Roman"'>。程序采用的是</span><span lang=EN-US>Windows
API</span><span
style='font-family:宋体;"Times New Roman"'>接口，全部采用</span><span lang=EN-US>C</span><span
style='font-family:宋体;"Times New Roman"'>语言编写，并未用到</span><span lang=EN-US>C++</span><span
style='font-family:宋体;"Times New Roman"'>的东西，所以也可以在其他的</span><span lang=EN-US>C</span><span
style='font-family:宋体;"Times New Roman"'>编译器，如</span><span lang=EN-US>Borland
C</span><span
style='font-family:宋体;"Times New Roman"'>，</span><span lang=EN-US>Watcom C</span><span
style='font-family:宋体;"Times New Roman"'>下编译通过</span><span lang=EN-US>(</span><span style='font-family:
宋体;"Times New Roman"'>可能有些函数的名称有些差别，所以建议使用</span><span
lang=EN-US>Visual C++4.0</span><span style='font-family:宋体;"Times New Roman";"Times New Roman"'>，</span><span
lang=EN-US>4.1</span><span style='font-family:宋体;

style='font-family:宋体;"Times New Roman"'>，</span><span lang=EN-US>5.0</span><span style='font-family:
宋体;"Times New Roman"'>版本都可以</span><span
lang=EN-US>)</span><span style='font-family:宋体;
"Times New Roman"'>。尽管在</span><span lang=EN-US>Windows3.x</span><span
style='font-family:宋体;"Times New Roman"'>平台上也能编译运行这些程序，但强烈建议使用</span><span lang=EN-US>Windows95</span><span
style='font-family:宋体;"Times New Roman"'>或</span><span lang=EN-US>Windows98</span><span
style='font-family:宋体;"Times New Roman"'>，因为</span><span lang=EN-US>32</span><span style='font-family:

'> <span
lang=EN-US>(2)<span style='font:7.0pt "Times New Roman"'> </span></span>
<span
style='font-family:宋体;"Times New Roman"'>既然是编图象的程序，当然要把机器的分辨率和颜色数调大一点了，这样显示出来的图象才显得漂亮</span><span
lang=EN-US>(</span><span style='font-family:宋体;
"Times New Roman"'>我用的是</span><span lang=EN-US>800*600</span><span

style='font:7.0pt "Times New Roman"'> </span></span> <span
style='font-family:宋体;"Times New Roman"'>图象处理的算法之中不可避免地要遇到一些数学的公式，霍金说过：“每多一个公式就要吓跑一半读者”，我将尽可能用通俗的语言将这些原理，公式讲解出来，力求做到公式尽可能的少；但遇到只有用公式才能讲明白的时候，我也决不回避，希望大家能耐着性子看下去。</span></p>
<p style='line-height:18.0pt'><span
style='font-family:宋体;"Times New Roman"'>本书主要参考的是我上数字图象处理课时的教材，作者是朱志刚老师，在此表示感谢。还要感谢我的好朋友袁昱，诸晓文和清华出版社的各位老师，没有他们的帮助，这本书的的出版是不可能的。</span></p>
<p style='line-height:18.0pt'><span
style='font-family:宋体;"Times New Roman"'>好了，不多说了，现在就让我们进入五彩缤纷的图象世界吧！</span></p>
