shows the segmented images obtained from the
CEFCM method. It is obvious that the CEFCM method outperforms the other color
object segmentation algorithms.

Conclusions
Video object segmentation has been recognized as a main technology to achieve
the content-based coding proposed in the MPEG-4 standard. In this chapter, we
proposed color eigenspace segmentation methods to extract the desired objects.
