File Information
Description

VFM allows Matlab to access video source devices such as frame-grabbers boards and USB cameras. Currently VFM has been implemented only for Microsoft Windows 95, 98 and NT. On these platforms, VFM uses Microsoft's Video for Windows driver model, to access video source devices on the system. Up to ten such devices can be present on the system, and accessed simultaneously. VFM provides functionality to connect to these devices to modify their properties, and to capture still image sequences in a format suitable for Matlab.
 
This package has been built for and tested on Matlab v5.

Great to know this exists! Problem though.. I find it very slow when capturing in a loop grab after grab... should I do this differently? I am trying to do some real-time DSP.

Hi all! It's really a cool tool!
But i have the same problem as Sylvain Chaminade. Does anyone here have an idea how we could solve that problem?

would be glad about an answer! :)
Thx guys!

Looks like it is not working very well under matlab 7 R14 ? Anyone had trouble too ?

16 Nov 2004 Sylvain Chaminade

excellent program! I use it for my researches! Really great except that I need 2 Webcams and I can't manage to switch from one to another automatically! Somebody know how I can do? Thanks.

Well and I need this type of projects very much. Thank You.

Excellent work. The programming interface is simple, but clear. No difficulties in installing this application. Very useful for those studying computer vision. I highly recommend this utility. To the author: THANK YOU.

Great Work!!

Thanks for this great project... I use it for my Matlab project and it works great.. I'll be sure to put your credits in my project...

Hi to all visual c++ programers
Thnaks a lot Mr. Pezeshkpoor due to this good project. I used it to communicate between my software and a CCD camera.
Best wishs

I can now use this vfm to access usb camera inside matlab. However, I
don't know how to use it for a multiple webcam setup. The
camera source can be selected by the mouse but not matlab
commands, any insight into this matter?

12 Nov 2003 Ruud Vinke

I have the same problem: i used borland c++ to compile, but apparantly some files are missing. Does anybody know what to do?

06 Oct 2003 Hossein Rezayi

Has complied anyone this project? I think some files of this project were changes or removed.
I couldn't complie it with Microsoft Visual C++6.
If it is possible please inform me.
Thanks

This is a nice software package. However, driver issues with multiple sources of the same type cause stability issues to pop up. Also, the limitation of Win98 and Matlab v5 make this an undesirable package for future use.

How can I connect two or more cameras and select one of them.

19 Apr 2003 henry rodriguez

como trabajar con los archivos vfm.
soy prinsipiante en este programa,cualquier ayuda me es muy importante

04 Apr 2003 Amin Abdul-Fattah

It works fine

23 Nov 2002 David Pais

Over Windows XP works so cool!!!. It's a great minitoolbox.

21 Nov 2002 Michael Wunder

Pretty good,...
but unloading the dll seems odd.
>> clear all
causes Matlab to crash

17 Mar 2002 Berthold Kaeferstein

Really cool stuff!
Even works under W2k with my Firewire camera!

THE VFM toolbox is an excellent tool for desktop image processing. The VFM toolbox provides simple access to any devices supported by the Video for Windows library (VFW.dll). I achived sampling rates up to 15 Hz for 640x480 RGB images. Note that Win32 platforms introduce signifcant jitter (~200 msec) when sampling images.

Very usefull programm! Thank you!
