A Survey of Facial Expression Generation Techniques Based on the Study Method[J]. Journal of Image and Graphics, 2009, 14(11): 2181. DOI: 10.11834/jig.20091101.
The expression generation is one of important research contents of intelligent human-computer interface.Because images are the research objects in the majority
the facial expression generation techniques based on the study method dont need to model for 3D faces and potentially can be of highly realistic expressions.These are of considerable advantages in reality improving and complexity reducing.Some methods can also be used to 3D models.The paper summarizes the published researches from the aspects of morphing
expression mapping
statistical method
2D meshes
facial color expression and performance-driven.The conceptions
principals and the methods of typical achievements are discussed.The features and existing problems of different algorithms as well as the development trend are analyzed.It provides some useful information and gives a reference to related works.
