android - 模拟器中的人脸检测 android + 网络摄像头预览

Question

我是 Android 模拟器的新手。谁能告诉我如何使用“android.media.FaceDetector”？我如何将网络摄像头预览与安卓模拟器中的人脸检测结合起来？

Answer 1

我不确定你在问什么； API 相当简单:

FaceDector fc = new FaceDetector(<width of your bitmap>, <height of your bitmap>, <max number of faces>);
Face[] faces = new Face[<max number of faces>];
int found = fc.findFaces(<your bitmap>, faces);
PointF point = new PointF();
for (int i = 0; i < found; ++i) {
  faces[i].getMidPoint(point);
  System.out.println("Point: " + point.x + ", " + point.y);
}
