| Description |
This report presents a computer model for the representation of human faces. This three-dimensional, parametric model produces shaded facial images. The face, constructed of polygonal surfaces, is manipulated through the use of parameters which control interpolation, translation, rotation and scaling of the various facial features. With this model, very little input information is needed to specify and generate a specific face with a specific expression. The model has been successfully used to produce a large variety of facial images and several animated sequences. The animated sequence illustrate the power of the model to change facial expression and conformation. Experience with the model indicates that fewer than 10 parameters must be manipulated to produce reasonable speech synchronized facial animation. Doctoral thesis. |
