Extracting Facial Motion Parameters by Tracking Feature Points
نویسندگان
چکیده
A method for extracting facial motion parameters is proposed. The method consists of three steps. First, the feature points of the face, selected automatically in the rst frame, are tracked in successive frames. Then, the feature points are connected with Delaunay triangulation so that the motion of each point relative to the surrounding points can be computed. Finally, muscle motions are estimated based on motions of the feature points placed near each muscle. The experiments showed that the proposed method can extract facial motion parameters accurately. In addition, the facial motion parameters are used to render a facial animation sequence.

Recently a new type of video coding method called model-based image coding has attracted much attention as a potential candidate for low bit-rate visual communication services. This technique reconstructs the facial image with a preknown three-dimensional (3-D) human face model and its received model motion parameters. The parameters of the head motion are mainly divided into two parts: global ...

متن کاملTracking Facial Feature Points with GaborWavelets and Shape
A feature-based approach to tracking rigid and non-rigid facial motion is described. Feature points are characterised using Gabor wavelets and can be individually tracked by phase-based displacement estimation. In order to achieve robust tracking a exible shape model is used to impose global constraints upon the local feature points and to constrain the tracker. While there are many application...
