Motion Detection in Kurento WebRTC

[abhay...@oodlestechnologies.com]

we are working on Kurento Media Server . We run all example of node.js like platedetector,pointdetector , crowddetector etc

We are facing problem how to detect motion . Let suppose if anything moves in front of camera and it detects any change then calls an event .

In simple words if anything moves in front of camera then we want trigger an Event

Thanks.

Hi,

Depends on how you define the thresholds for events, maybe you could use the crowd detector filter for that. Although it is meant to detect masses of people in an area, it basically looks for differences against the background, so provided the person is close enough to the camera, it would be seen as a "blurry mass" against the background, and therefor detected as a crowd :-) Anyway, remember that this filter has a different purpose, and the behaviour can be different as expected.

In any case, it would be easy for you to implement this filter yourself, and use it as an external module.

Cheers,

Ivan Gracia

 Thanks for your reply,

  It would be very helpful if you could provide any URL or doc/pdf file, where i can read it from & implement

Well, we have documentation on how to create your own modules for KMS. As for what to put in the module itself (i.e. the GStreamer code), nothing beats good old google ;-)

• Documentation about module creation in Kurento
• Some motion detector implementations
• https://github.com/codebrainz/motiondetector
  
• https://gitorious.org/gstreamer-motion-plugin
  
• https://bugzilla.gnome.org/show_bug.cgi?id=629244

I think that's a good start ;-)

In this youtube https://www.youtube.com/watch?v=r91nExNEHiw we see motion detection . Can we get this module

That module is not open source.

Best.

Ok so for our requirements we need to implement a module . But we are Java Developers  is there any way to write code in Java for motion detection module . i go through the below link  

• https://github.com/codebrainz/motiondetector
  

but the code is written C language, 
can kurento provide streaming via CCTV / IP cameras?

You cannot create your motion detection algorithm in Java in Kurento (for performance reasons, it's not a good idea to implement such thing in Java even out of Kurento)

If you are really desperate for having such module, you may use Kurento professional support for creating such algorithm, drop a message to in...@kurento.org for further info.

can kurento provide streaming via CCTV / IP cameras?

Yes, as long as the cameras support RTSP or HTTP media streaming. For analog cameras, you need to have a device for transforming the stream to IP, there are many such devices in sale on major camera vendors (Axis, Bosh, etc.)

Best.

Hello Luis & Ivan
Is this work for us ? https://github.com/Kurento/kms-filters/tree/master/src/gst-plugins/movementdetector . We need if there is any movement on screen then it triggers  an Event and we implement our code after triggering that event

Hi Abhay,

Are you still working on kurento filters ?
Can you please provide some help regarding how these filters (written in C) are interacting with Java modules or there are separate implementations for them ?

Thanks in advance
