Kinect的體色

Question

我寫要求的背景去除（其中玩家）的應用程序，並與一些顏色或任何字符（如https://stackoverflow.com/questions/10599658/how-to-create-kinect-avatar）屏蔽用戶身上。
在此先感謝

Channel 9的教程儘管處於舊版測試版2中，但很容易轉換。這裏是最終的代碼（轉換）

public static class KinectExtensions 
    { 
     public static WriteableBitmap CreateLivePlayerRenderer(this KinectSensor sensor) 
     { 
      if (sensor.DepthStream.FrameWidth == 0) 
       throw new InvalidOperationException("Either open the depth stream before calling this method or use the overload which takes in the resolution that the depth stream will later be opened with."); 
      return CreateLivePlayerRenderer(sensor, sensor.DepthStream.FrameWidth, sensor.DepthStream.FrameHeight); 
     } 

     public static WriteableBitmap CreateLivePlayerRenderer(this KinectSensor sensor, int depthWidth, int depthHeight) 
     { 
      AllFramesReadyEventArgs d = new AllFramesReadyEventArgs(); 
      using (DepthImageFrame depthImage = d.OpenDepthImageFrame()) 
      { 
       WriteableBitmap target = new WriteableBitmap(depthWidth, depthHeight, 96, 96, PixelFormats.Bgra32, null); 
       var depthRect = new System.Windows.Int32Rect(0, 0, depthWidth, depthHeight); 

       sensor.DepthFrameReady += (s, e) => 
       { 
        Debug.Assert(depthImage.Height == depthHeight && depthImage.Width == depthWidth); 
       }; 

       sensor.ColorFrameReady += (s, e) => 
       { 
        // don't do anything if we don't yet have a depth image 
        DepthImageFrame colorImage = depthImage; 
        if (colorImage.BytesPerPixel == null) return; 

        byte[] color = new byte[sensor.ColorStream.FramePixelDataLength]; 
        e.OpenColorImageFrame().CopyPixelDataTo(color); 

        byte[] output = new byte[depthWidth * depthHeight * 4]; 

        // loop over each pixel in the depth image 
        int outputIndex = 0; 
        for (int depthY = 0, depthIndex = 0; depthY < depthHeight; depthY++) 
        { 
         for (int depthX = 0; depthX < depthWidth; depthX++, depthIndex += 2) 
         { 
          short[] bits = new short[colorImage.BytesPerPixel]; 
          depthImage.CopyPixelDataTo(bits); 
          // combine the 2 bytes of depth data representing this pixel 
          short depthValue = (short)(bits[depthIndex] | (bits[depthIndex + 1] << 8)); 

          // extract the id of a tracked player from the first bit of depth data for this pixel 
          int player = bits[depthIndex] & 7; 

          // find a pixel in the color image which matches this coordinate from the depth image 
          int colorX, colorY; 
          ColorImagePoint colorPoint = depthImage.MapToColorImagePoint(depthImage.Width, depthImage.Height, sensor.ColorStream.Format); 


          // ensure that the calculated color location is within the bounds of the image 
          colorX = colorPoint.X; 
          colorY = colorPoint.Y; 

          output[outputIndex++] = color[(4 * (colorX + (colorY * e.OpenColorImageFrame().Width))) + 0]; 
          output[outputIndex++] = color[(4 * (colorX + (colorY * e.OpenColorImageFrame().Width))) + 1]; 
          output[outputIndex++] = color[(4 * (colorX + (colorY * e.OpenColorImageFrame().Width))) + 2]; 
          output[outputIndex++] = player > 0 ? (byte)255 : (byte)0; 
         } 
        } 
        target.WritePixels(depthRect, output, depthWidth * PixelFormats.Bgra32.BitsPerPixel/8, 0); 
       }; 
       return target; 
      } 
     } 
    }
