Two web cams are connected to pc which will be continuously capturing the video streams of two different locations. Frames are to be analysed continuously at about 10 FPS rate and to be compared with a master frame. When there is found diferrence( detectable contrast difference) in comparision, massage "fail" is to be provided. If the image matches with the master, massage "pass" is to be provided by serial communication.
This job can be done on Windows or Linux Platform and the solution will be provided with sourcecode.
