i wrote this for Matlab 7.7.0 (R2008b)
this gui should make it convenient to access usb or firewire cameras (or whatever Matlab toolbox supports), and helps to quickly access camera settings, as well as record streams and access streams (frames) for real-time image processing
it requires the image acquisition toolbox
start CameraGUI: just call 'CameraGUI' in Matlab command line
the GUI also provides an interface for directly recording stream to disc (either as uncompressed avi, or as matlab arrays),
as well as a function to access frames in real-time to do some real-time image processing on the incoming stream: modify file 'RealtimeProcess.m' line 140
i also inlcuded a small script showing how to access the gui handle from another application (execute scipt 'openCameraGUI.m')
