The Real-time video composition technologies of Ladybug Mixer are suitable for surveillance applications such as Homeland security. Surveillance requires videos to be capatured in multiple sites simultaneously. If there is no motion in the video capture, the record switch will not be turned on. When motion is detected the recorded video can be sent to a information center through broadband and raise an alarm.

Motion Detection

Suppose two pictures are A and B, we can compare A and B to see if they are the same. A xor (not B) is a simple computing. If B is the same as A its result is 0. This simple computing can be implemented by HLSL. This is a simple motion detection, in which a video is compared to a still picture: a non-black video will be displayed.
