fuzz buster, anyone?
The state of the art in vision technology is at least a couple of decades off from having this capability, the best you could do is maybe recognize all cars of a certain color, but to distinguish a certain make, model, and then whether it is an undercover police car is well above and beyond what vision recognition to do espcially police cars that humans have a hard time determining as police cars. And that facial recognition in airports is WAY more talk then a practical reality.Originally Posted by Curiosity
I forget what its called... the DoD is playing with air-bourne lazers to identify aircraft model (and thus country of orogine) Apparently it will have a ridiculous range (limitless as long as its line-of-sight)Originally Posted by god_of_cpu
I have a QuickCam Orbit that has pan/tilt and zoom.... and a 1.3 megapixel CCD. It would be good for being behind a cop on the highway trying to see if that really is a cop way up there. The software that comes with it includes a face-tracking mode (for video confrencing) that could be adopted, as well as an intuitive control panel that SHOULD be adopted for touch screen:
This is a great idea. I've got a lot of cops around my area now that have laser and I've avoided so far by seeing them before they saw me and slowing down but they're getting better with range. If I could see down the road some distance I would just be money. Great idea and kudos to anyone who gets it working.
around me cops drive crown vics, imapalas, explorers, cameros, and im pretty sure there was a contour. im sure there are more... (yes all these cars are unmarked)
rebuilding carpc... kinda..
I dont know abot zooming but as far as controlling a cam, i was thinking of using the wiring and servos from a remote car mirror. mount the cam to that and use the lil joystick control to move the camera instead of a mirror
Most of those face tracking algorithms are actually just motion tracking algorithms. i.e. they look for the biggest moving thing in the image and follow it not so much the thing that looks closest to a face, seeing as when in a vehicle everything around you appears to be moving, I don't think you would have much luck tracking a cop car or anything for that matter this way.Originally Posted by EBFoxbat
The only realistic vision based way to doing this is to find something extremely distinctive that all cop cars have. Those spot lights that always allow me to tell whos an undercover would be good except that they look just like other things found on all sorts of cars, like regular lights or chrome wheels. Police lights would be a much more attainable goal. Tracking globs of red and blue within a relative horizontal proximity to each could be done with just an HSV conversion and the appropriate thresholding for the proper colors then your problem just becomes finding two appropriate sized dots in a binary image, a much easier problem to solve. This would rule out tracking undercovers, but shouldn't have many false positives.
So track the object not moving... the still car on the mooving road.Originally Posted by god_of_cpu
Ever seen Bruce Willis in The Jackal? My Orbit has all the build in features (cept it goes for about $120 retail) Somoene would just have to write an easier-to-use program to control it.and use the lil joystick control to move the camera
I'm thining about doing this secondary to my carputer... maybe another smaller system.
This is called Catch Ken and is used by the dutch police. You guys probably don't read german, maybe translate it through the net or just have a look. Here's a run down:
Catch Ken recognizes (!) the square of the license plate and then analyzes the characters on it. It is hooked up with a DB of all license holders + wanted fellons. It also trip-tracks (point-to-point measuring for speeding).
The software runs on XP and is flexible in the sense that it can be hooked up to most DB's (Acces, Mysql, etc.)
If you look around on the site you'll also find the special tilt/pan cams and dedicated hard drives. Mind you, everything runs in video res and color.
All this stuff might be out of our league.(price/gov. org. only?).
But hey, know thy enemy.

I still think it would be usefull. Maybe constantly record the last 5 minutes of drveing and just have it write over itself so as not to waste HDD space, but it sure would help when you say "no that old ****** pulled out in front of me, i swear!"
