推荐答案

// Assume frame variable contains a FaceTrackFrame.

EnumIndexableCollection<AnimationUnit, float> faceAUs =
    frame.GetAnimationUnitCoefficients();


for (int index = 0; index < faceAUs.Count; ++index)
{
    Debug.WriteLine(string.Format("{0}: {1} = {2}", index,
                    (AnimationUnit)index, faceAUs[index]));
}

在调试器输出窗口中生成以下信息（当然，您的数字会有所不同）：

which generates the following info in the debugger output window (your numbers will vary, of course):

0：LipRaiser = -0.0482193

1：JawLower = 0.2953424

2：LipStretcher = -0.587648

3：BrowLower = 0.05249858

4：LipCornerDepressor = 0.2725175

5：BrowRaiser = -0.2865464

0: LipRaiser = -0.0482193
1: JawLower = 0.2953424
2: LipStretcher = -0.587648
3: BrowLower = 0.05249858
4: LipCornerDepressor = 0.2725175
5: BrowRaiser = -0.2865464

使用这些值，以及所选点的相对位置在嘴和眼睛区域周围，可以检测面部表情图案。希望这会有所帮助。

Using these values, along with relative positions of selected points around the mouth and eye areas, it may be possible to detect facial expression patterns. Hope this helps.
