The conventional approach
for object detection with real-time results would be to perform
flesh toning of the entire image region to focus on a particular
region of interest and return this area to be tracked continually
[3]. One of the advantages of employing the Viola and Jones
over this conventional approach is its success in terms of
running its detector on the entire image and yet achieving realtime
results of about 15 fps on a conventional 700 MHz
Pentium III [2].
