OpenCV supports writing to JPEG with compression arguments.

Or in android

If you require compressing to a ZIP or tarball there are android versions of these around. If you search the internet.

Hi all,

I am attempting realtime marker tracking using the ARUCO Library to do my tracking.

I have noticed and read that USB cameras come with processing overhead and thus give poor frame rates. I have also observed that mobile phone camera AR applications give better frame rates.

I have looked into using the raspberry pi, but alas until the camera module comes out I cannot get reasonable frame rates from USB camera solutions. Unless there are others?

What is the best platform I can use for a realtime embedded AR system?

are you able to compile OpenCV for the native architecture (assuming x86). What operating system are you using?
