-ProxyTrans transform filter would call your function as a callback
-on every frame instead of processing the image itself. If you
-create a filter graph with your application, insert the proxy
-filter before renderer (or at any other place you like) and set a
-callback function defined in the application; the proxy implements
-the special interface for such case -- IProxyTrans. Then start the
-DS and every frame will be processed with your function. You can
-find the binary of ProxyTrans in Bin folder of your OpenCV
-installation. Here is the example of using ProxyTrans. Also refer
-to Apps\Hawk\MainFrm.cpp and Apps\Hawk\AviSource.cpp.

-#include <iProxyTrans.h>
-#include <ProxyTransuids.h>

-void callback(void*);

-int Initialize()
-{
-/* Initialize the source filter, filter graph.
-Find the samples of those in Apps\Hawk\MainFrm.cpp, functions
-CMainFrame::CreateCamera and CMainFrame::CreateFilterGraph */
