A MATLAB interface to grabbing live video (analog/digital) images through XVision2. You do not need XVision2 to use this, but you will need a ieee1394 firewire camera installed or a BT Frame Grabber. This package has been implemented and tested on Linux 2.4 kernels and will not function in windows.
This package contains an interface for snapping images from a video-stream while inside of MATLAB. Jason Corso (email@example.com) v1.0 It uses XVision2 on the backend as the video grabber and shared-memory to actually transfer the image. Package Contents: Makefile -- in case you need to make and change snapvideo.cc snapvideo.cc -- the server program that grabs images. snapvideo -- the i386 binary server program snapper.c -- a test c program that acts as a client and gets the most recent image from the server and saves it as foo.ppm snapper -- the i386 binary test client program mex_snapper.c -- the mex source interfaces with matlab and the server included in case you need to make a change. mex_snapper.mexglx -- the binary file needed in your working directory for this to work. xv_snapshot.m -- the matlab m-script which is called from matlab README -- this file. To Run: 1 - start the server ' %> snapvideo bt ' for analog Bt8x8 video ' %> snapvideo dig ' for digital ieee1394 video 2 - from inside of matlab ' > I = xv_snapshot; ' will grab an image ' > imshow(I); ' will show the image 3 - kill the server when you are done by typing ctrl-c NOTE: You must send the program a SIGINT in order to allow it to detach and delete from shared memory segments and semaphores.
