Description: In this paper we present a scheme for integrating a digital stabilizer with video codec of a digital video camera. This integration achieves computational efficiency without affecting the performance of video coding and digital stabilization. The proposed scheme achieves this by confining the global motion estimation to within a small background region determined by clustering the motion vectors generated by the video encoder.- In this paper we present a scheme for integrating a digital stabilizer with video codec of a digital video camera.

Description: 环境的搭建：
1、新建一个Web工程.
2、在工程的src下新建一个包smart.jrsoft.video.
3、将Source下的ChangeVideo类拷贝到新建的包smart.jrsoft.video里面.
4、将Enviroument里面的makeing.bat和encoder.bat文件放在c盘根目录下面.
5、将Enviroument里面的ffmpeg.exe文件放在windows-->system32下面.
6、运行ChangeVideo里面的main方法就可以试用啦.
注意事项:
1、Enviroument文件夹里的vcastr21.swf是一个流媒体播放器.
2、Jsp文件夹下面的JSP页面是调用这个播放器的例子.
3、如果需要改变截视频图的大小可以修改makeing.bat文件(用记事本打开修改即可).-Built environment:
1, create a new Web project.
2, create a new project under the src package smart.jrsoft.video.
3, the Source under the ChangeVideo copied to the new class inside the package smart.jrsoft.video.
4, the Enviroument inside makeing.bat and encoder.bat files in the directory c packing.
5, the Enviroument inside ffmpeg.exe files on windows-> system32 below.
6, running ChangeVideo inside the main method can try啦.
Note:
1, Enviroument folder inside vcastr21.swf is a streaming media player.
2, Jsp folder, call the following JSP page is an example of this player.
3, if you need to change the cross-sectional size of the video map can be modified makeing.bat file (use Notepad to open modification).
