特效算法、库和书籍
I am looking at The Special Effects In Picasa article.
Where can I find the following:
- C/C++ or Java open source library to do it
- Good books and/or articles to learn the algorithms how to do it myself
Thanks in advance for your help.

您可以通过颜色操作（白平衡）和白平衡来实现该页面上的大部分效果="http://en.wikipedia.org/wiki/Gaussian_blur" rel="nofollow">空间过滤。
在您使用库来实现此目的之前，我建议您尝试一下图像处理软件，例如 GIMP 和试图复制效果。当您确定自己知道自己在做什么后，请继续尝试编写代码。
对于库，请查看 opencv。如果您选择的是该语言，那么还有该库的 Java 包装器（Java 有自己的语言）图像库也是如此，但我没有使用过它们）。对于书籍，我个人最喜欢的是 Gonzalez & Woods——前几章将帮助您入门。对于文章，Google 是您的朋友。
You can achieve most of the effects on that page by color manipulation (white balance) and spatial filtering.
Before you go down the path of using libraries to achieve this, I recommend playing around with image manipulation software like GIMP and trying to replicate the effects. After you're sure you know what you're doing, go ahead and try and code it up.
For libraries, have a look at opencv. There are also Java wrappers for that library if that is your language of choice (Java has its own imaging libraries as well, but I haven't used them). For books, my personal favorite is Gonzalez & Woods -- the first few chapters will get you started. For articles, Google is your friend.
