8 Conclusions and Future Works
A new method for face tracking and detection has been presented in this study, which has
been designed to detect frontal faces in color images without a priori knowledge about the
number of faces or the size of the faces in a given image. All our experiment results show that
the proposed method can obtain high detection rates in the presence of both simple and com-
plex backgrounds. SM detection may not be suitable for certain cases, such as when there are
colors in the image that resemble the skin, but are not skin pixels. To overcome this problem
OM transform could be employed to correctly detect the face region in the SM image. The on-
going work involves increasing the speed of our proposed method as well as adopting par-
allel processing provided by GPUs. In addition, the method is also being adopted as a pre-
processor for a face recognition system, such that false positives may be rejected by the face
validation process of the recognition system.
