Thread: Calling Any Java Programmers - Computer Vision Project

actually java is perfectly suited for this sort of thing. C# is basicly nothing more then a ripped off copy of java. Java has had Generics and other powerful features in place long before dot net. And portibibly is key here, what if you want to the core classes of the SDK he is writing on systems other then windows systems (which for this application is very likely) Current OEM automakers might love this technology, but it will do them no good if it is in dot net.

BTW I still have to get a video capture device to try this out, I dont know much about them so i have been tring to learn, is there a capture device that you suggest sama?

@ ElKEed



and that I have experience in Java/Vision/AI together + that I work with Java every day

.net is write in any language and run on windows (mainly), java is write in one language but run anywhere. It means that Linux/Mac users can also benefit from this project

Saying that, to make sure that everyone can take part, perhaps the framework can allow an algorithm to be defined outside of java, in a text file, and java would import it. in this way, mathmaticians with no java experience can write algorithms, whilst the algorithm modules can be used by application writers.

@alti
regarding a capture device, anything will do realy. as long as you can get a decent framerate. I'm currently using a webcam, but that has some major woes: it changes intensity when it wishes! I hope I can change that in software.

when you do get some time and you can capture, could you post/send me some footage from a night vision camera? I'd like to see what can be done with them.

sure thing, I ordered this today as a capture device, hopefully I can get my camera reassembled pretty quickly (right now it is in peices waiting to be installed in the car) in the interest of time, I might forgo the HUD i had planned temporarly and just use the computer to view the image.

I'd be interested in helping with some of the algorithms. I have a strong math background, but a limited amount of programming experience. I have a little experience with some AI classes I've taken, just enough to get me interested.

I'll take a look at your attached file this week when I get some free time. This is definately promising

excellent!

I'm almost certain that to get motion detection whilst moving requires optic flow. Whilst I understand the high level concept, my maths aint great when it comes to reading greek! But I can understand it once it's in an algorithm that I can use.

If you don't mind, see if you can make sense of what this guy's talking about. I know that wavelets are a super elegant and fast way to do lots of different comupations. This guy proposes a method for doing optic flow using it. beyond me for now!

added instructions in the first post to get the code up and running. So any new comers aren't scared away


hi pronerd. if you can give feedback on how it's working for your future setup, that would be more than enough contribution. Of course you're welcome to mess with the code

sorry it took so long, but i finally took the first step and tested it out.

I cant seem to get it to work though, I have my cam up and running in centrafuse and in jmStudio (I can start capturing and it works) but in your program all i get is a black screen???

I will play more and post some screen shots, do you think this is because the camera is b/w?? I wish i had a color camera to test it... hmmm, maybe i will pick up a cheap web cam.
