We introduce an efficient approach for representing a human face using a limited number of images. This compact representation allows for meaningful manipulation of the face. Principal Components Analysis (PCA) utilized in our research makes possible the separation of facial features so as to build statistical shape and texture models. Thus changing the model parameters can create images with different expressions and poses. By presenting newly created faces for reviewers' marking in terms of

With feature selections, we sort those parameters by their importance in deciding the three aforesaid aspects.
