如何使用tensorflow.js面部地标检测模型获取面部的特定标志，例如嘴唇或眼睛

我正在尝试改变眼睛和嘴唇的形状和位置，为此我使用tenserflow.js人脸特征点检测模型 https://github.com/tensorflow/tfjs-models/tree/master/face-landmarks-detection。我得到了所有 468 个面部标志，但问题是我不知道，而且我从未在互联网上找到任何解决方案如何获取仅需要的标志（例如嘴唇和眼睛）的位置。我得到了所有的要点，但想在嘴唇和眼睛上应用更改，我如何仅在这些地标上应用更改。

的坐标可用here https://github.com/tensorflow/tfjs-models/blob/master/face-landmarks-detection/src/mediapipe-facemesh/keypoints.ts.

您可以参考网格图像示例 https://github.com/tensorflow/tfjs-models/tree/master/face-landmarks-detection#keypoints其中也有点，但您需要放大并手动检查它们。

这些是您的用例所需的确切坐标。
