video detection for emergency case

hi I'm doing my final year project about video detection for emergency case in tunnel using matlab. What is the best technique to use ?? where can i find references, journals,and articles about the subject ,specially for video detection and comparing the videos ??? UR help will be highly appreciated... Thanx

What is "emergency case" in this situation?

Note: MATLAB is not designed for use in emergency or life-threatening situations.

What is an "emergency case"? While a fire can be detected by heat and smoke sensors much more reliably than with a video analysis, a pregnant woman, which needs a midwife for a birth assistance urgently is hard to recognize, especially if there is only one camera every 200 meters. Before you can bild an efficient event detector, you have to define as precise as possible, which events you want to detect, and which count as noise.

I do believe, that such topics are investigated seriously and a reliably working system could save human lifes, the most expensive item. But the desaster would be enormous, when such a system fails, and I haven't seen a bug free program, especially when one has to consider the operating system, java, the video drivers and the analysis software. Therefore the most reliable strategy is a life-stream of the video to youtube and the Matlab program counts the hits&likes in real time using URLREAD. A peak in the counter will signal an emergency.

Sorry for this pessimistic estimation. I'm sure serious scientists working in the field of image analysis have more substantiated suggestions. And I hope, that no tunnel is controlled only by Matlab driven automatic warning systems.

The emergency case i meant is something like car crash or water flood in the tunnel,the code should like showing the video coming from a cam, then analyse it,compare it to the original case, and then alarm if there is any emergency case like what i said before (car crash or water flood).

Is the flood to be measured by depth or by energy of the filling stream?

Is a car that is parked (or stopped voluntarily, or stalled) to be distinguished from a car crash?
