我曾经在Ubuntu 12.04.1上使用OpenCV 2.4.5和一些特定的配置和软件包,但是在Ubuntu 12.04.2上升级到OpenCV 2.4.6.1时遇到了问题

我想分享一些想法(从包括SO,ubuntu.org,asklinux.org和其他许多来源的几个来源收集的值得注意的信息汇编;当然还有尝试几个程序)

以下是最终让我了解的内容.

注意:确保卸载先前安装的OpenCV,FFMpeg和其他依赖项的任何先前安装.

第1步(安装ffmpeg和依赖项)

# goto http://sourceforge.net/projects/opencvlibrary/files/opencv-unix/
# download the latest stable opencv such as 2.4.6.1 (http://sourceforge.net/projects/opencvlibrary/files/opencv-unix/2.4.5/opencv-2.4.5.1.tar.gz/download) to current directory (such as home or ~/Document)
# cd /opt
# tar -xvf <path-to-download-folder>/OpenCV-2.4.6.1.tar.gz
# cd OpenCV-2.4.6.1
# create a foler under current dir (following previous step, this should be <opencv-dir>), called prepare
# cd prepare
# Copy the following script to gedit and save as install.sh to current dir, this should be <opencv-dir>/prepare
# Check corresponding …

我需要在已定义 POJO 的列表中动态排除某些属性。要序列化的主要 POJO 是：

public class Foo
{
    List<Bar> bar;

    public void setBar(List<Bar> bar)
    {
        this.bar = bar;
    }

    public List<Bar> getBar()
    {
        return this.bar;
    }

    public static class Bar
    {
        private int id;
        private boolean ignoreId;
        private String name;

        public void setId(int id)
        {
            this.id = id;
        }

        public int getId()
        {
            return this.id;
        }

        public void setIgnoreId(boolean ignoreId)
        {
            this.ignoreId = ignoreId;
        }

        public boolean isIgnoreId()
        {
            return this.ignoreId;
        }

        public void setName(String name)
        {
            this.name = …
