Hadoop上结合opencv\javacv

mac上安装opencv

1. 去 http://opencv.org 下载最新版OpenCV for Linux/Mac源文件，目前版本是2.4.3。下载后解压。
2. 去 http://www.cmake.org 下载最新版cmake，.dmg文件，目前版本是2.8.10.2。下载后安装。
3. 接下来开始安装opencv
    开一个终端，进入opencv解压缩的目录，如cd 而后把文件夹拽进去。
    mkdir release
    cd ./release
    cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D BUILD_PYTHON_SUPPORT=ON -D BUILD_EXAMPLES=ON ..
    make
    sudo make install
4. 至此opencv应该已经装上了。
        注：若是cmake出现错误，请到苹果开发者网站那里下载Command Line Tools安装。（关键）

Hadoop Streaming does nto really agree with binary data, so I wouldn't go there. 
You will have to write both a custom Input/OutputFormat in Java plus the face-detection code in C++ (see http://wiki.apache.org/hadoop/HadoopStreaming ) 

Why not use OpenCv Java bindings? ( http://docs.opencv.org/java/ ,http://docs.opencv.org/doc/tutorials/introduction/desktop_java/java_dev_intro.html )

 

opencv如何从内存读取图像数据？

若是你的每一帧数据都能获得
IplImage* img=cvCreateImageHeader(cvSize(1920，1080),IPL_DEPTH_8U,3);//3表示24位，灰度请改成1
img->imageData  = 你的帧内存数据;
接下面你能够处理这一帧图像了
