Hompus.VideoInputDevices
DirectShowLib.Standard
OpenCvSharp4
OpenCvSharp4.Extensions
OpenCvSharp4.runtime.win
ViewFaceCore
ViewFaceCore.all_models
ViewFaceCore.Extension.SkiaSharp
ViewFaceCore.runtime.win.x64关键代码如下所示通过OpenCvSharp从摄像头获取图片后调用ViewFaceCore模块识别图片中的人脸并用红框标记人脸最后显示图片。
m_capture.Read(m_image);if (m_image.Empty())return;Bitmap image OpenCvSharp.Extensions.BitmapConverter.ToBitmap(m_image);var bitmap SKBitmap.Decode(m_image.ToBytes());
FaceDetector faceDetector new FaceDetector();FaceLandmarkConfig config new FaceLandmarkConfig();
config.MarkType MarkType.Normal;FaceLandmarker faceMark new FaceLandmarker(config);FaceInfo[] infos faceDetector.Detect(bitmap);using(Graphics graphics Graphics.FromImage(image))
{for (int i 0; i infos.Length; i){graphics.DrawRectangle(Pens.Red,infos[i].Location.X,infos[i].Location.Y,infos[i].Location.Width,infos[i].Location.Height);}
} faceDetector.Dispose();
faceMark.Dispose();pictureBox1.Image image;最后是程序运行效果在手机的B站上找了“花都兄弟”的视频对着摄像头播放可以看到能够识别到人脸并标记。
