The hardware architecture comprises a commercial camera, a frame grabber,
and a Pentium II 230 MHz. The camera used is a commercial camera Flexcam
ID, manufactured by Videolabs, equipped with manual gain control. It has
a resolution of 640x480 pixels per interlaced image. The frame grabber
is a PXC200 manufactured by Imagination. The input camera image is digitized
by the board and even and odd fields of the image are separated for future
processing at 60 Hz and transferred to memory through the PCI bus. All
further computations are performed with the PC. We achieved a total processing
time of 14ms per frame. The next figure shows the graphical user interface
(GUI) of the windows-based application that runs our program.
