使用 AForge 对 Kinect 视频进行 C# 图像处理

我的目标是：
使用Kinect视频进行形状识别（图片上的大矩形），在图片上绘制矩形以突出显示结果并显示。

我使用的技术：

• C#代码，
• AForge，更具体地说是它的形状检查器

http://www.aforgenet.com/articles/shape_checker/

魔法应该如何运作：

1. 每次帧准备就绪时，我都会将帧数据作为字节数组获取，并将其转换为位图以允许我对其进行分析
2. 应用形状识别算法
3. 渲染结果...

我的问题 ：
到目前为止，整个过程有效，但是当我尝试在 WPF 图像中呈现结果时，它非常滞后......（每 10 秒 1 帧）...

我的代码：

// AllFramesReady is called every time a frame is ready to use...
private void AllFramesReady(object sender, AllFramesReadyEventArgs e)
    {
        using (ColorImageFrame colorFrame = e.OpenColorImageFrame())
        {
            if (colorFrame == null)
            {
                return;
            }
            _Pixels = new byte[colorFrame.PixelDataLength];
            colorFrame.CopyPixelDataTo(_Pixels);
            // Analyze the image
            int stride = colorFrame.Width * 4;
            System.Drawing.Size size = new System.Drawing.Size(colorFrame.Width, colorFrame.Height);
            // get the bitmap from bytes
            Bitmap btmap = BytesToBmp(_Pixels, size);
            //analyze the data...
            btmap = _shapeReco.AnalyzeImage(btmap);
            // copy the new data back to pixels
            _Pixels = BmpToBytes(btmap);
            // rendering the analyzed image
            imageAnalyzed.Source =
                BitmapSource.Create(colorFrame.Width, colorFrame.Height,
                96, 96, PixelFormats.Bgr32, null, _Pixels, stride);
        }
    }

我可以提供完整的代码（MV C# 2010项目...我感谢任何帮助！

谢谢。
