Hello Michael

Did you ever manage to get the jAi ethernet camera working with matlab? Im having similar problems and would like to know if its possible.

Yes, i have.
I the new Matlab 2009 and with its possibility to load a .NET DLL file.
I've written a small DLL in C# which is able to set some parameters and to make an image.
You can easily use the functions in the DLL in Matlab then.
A negative effect of that method is, that it requires a little bit of time to call the function in the dll and to hand over the imagedata. I've made a "liveview" in the way that i capture an image in a loop. But there are only 15fps possible instead of the 30 which the cam supports.

If you want to have more information, feel free to contact me.

I am trying to create a small interface with a live view that is able to save 4 images in quick sucession. But i am needing help gettin matlab to talk to the camera. I would be very greatful if i could see your code, my personal email is "adam_bird_ at hotmail.com"

Thankyou very much

I am also trying to do something similar. I have already written working c code to capture successive images from the camera but am not sure how to actually display them in matlab. I've tried using imshow but it only updates with the last image, not for every frame. I'm curious to learn how you accomplished this? Thank you very much!!

Hi max,
I would be very interested to see the code that you are working on, i am still struggling to get matlab to talk to the camera, what version of matlab are you using?

Cheers
