应用场景 画面遮蔽侦测主要应用于一些强制性开放的视频地点，如：煤矿矿产区，或者是一些特定的娱乐场所，这些视频在一些时候通常是要作为“现场证据”来呈现的，而有人的却可能由于各种原因，不想让视频给录下来…这个模块的目标就是检测出画面遮蔽，并告警通知相关人员去进行必要的处理。 工作原理 先将视频进行灰度处理，然后进行背景、前景差检测画面的差异，并检测差异部分是否是大片连续的，若是则认为画面被遮蔽。 补充说明 由于本算法对其应用场景有一定的特殊要求，若是放到不太合适的地方容易出现许多误报的状况。 以下是接口说明。 函式功能规格说明 全域类别说明 class CMaliciousDetect{ private: bool bAlarmFlag;                                   //发出警告的bool variable int nAlarmTimer;                             //警告时间 int nWidth, nHeight;                       //Frame之宽高 bool IsSetted;                                         //background是否设定变量 IplImage *Frame;                                   //input image IplImage *Gray;                             //把input image转换成gray level IplImage *C_edge;                       // The edge value image IplImage *BG_edge; IplImage *_small; […]

Using haarcascade_frontalface_alt to implement “passenger flow statistics”.

This version is rebuilt by using the source code recovered from the backup svn repository(I’d encountered with a hard disk collapse a year ago, and lost almost all my data). This means this version has some known bugs, and some new features once EzStreamSvr had are no more supported. But […]

其实关于新版VLC无法看RTSP的视频的问题早在很久之前就已经有人跟我提过了，而我写的EzStreamSvr和EasyIPCam都是用RTSP来streaming 视频的，因此又有一些朋友来把这个问题反馈回来给我，为以省去更多的口舌，特将此问题整理如下：

Actually the first version of RG4.NET was using wordpress as my blog app, but it’s templets are really hard to maintain for myself comparing to DedeCMS, so a year before, I migrated RG4.NET to DedeCMS. But as time goes by, I changed my mind, I think RG4.NET should be a […]

经过两周的投票，最终的结果是EasyRTMP和RTSPPlayer的人气高一点，十一后又加了两天，结果EasyRTMP拔了头，坦白说，这个结果是让我有点失望的，因为无论是技术上讲，还是从实用程度上来说，这两个明显不是最能“引导流媒体潮流”的东西，尤其是EasyRTMP更甚。 而从另一个角度来看，流媒体开发论坛上这么多人，流媒体开发群里有那么数百个人，这个投票搞了将近两个星期也就这么三十几个人，如此看来真正对开源项目感兴趣的人还真少，更别提会去做开源项目了。 罢了。

Just as the title I posted, words of this month is “Ignorance is bliss” For all kinds of reasons, I submitted my job quit request earlier in this month, so this month is meant to be a big month in my life. Till now, I dont know what to say. […]
