A critical analysis of facial animation based on emotional condition and facial skin colour

The research on facial animation has grown very fast and become more realistic in term of 3D facial data since the laser scan and advance 3D tools can support creating complex facial model. However, it’s still lacking in term of facial expression based on emotional condition. Facial appearance changes as people talk, move and, change expression. The key indication of this change is the skin colour. Facial skin colour is one parameter that is contributing on augmenting the realism of facial expression, because it’s closely related to the emotion which happens inside the human.
