Automatic detection of heads in colored images
José Antonio García, Niels da Vitoria Lobo, Mubarak A. Shah, Jeffrey A. Feinstein · 2005
We use shape based searching to detect head contours of arbitrary size in single images. We begin by looking for a head model which is optimal for finding head contours of various orientations. Then we develop a search technique for finding contours of arbitrary size, and present a way in which the search space can be narrowed using color and intensity gradient information. We show results and discuss how the method could be improved.
