我試圖通過打開或眯着眼睛來放大和縮小來自攝像頭的實時視頻流的每個幀。我已經有了眼動追蹤部分,但我無法弄清楚ScaleTransform中的哪個部分。下面是我現有的代碼:如何使用WPF中的眼動跟蹤來縮放圖像?
using System;
using System.Collections.Generic;
using System.Windows.Forms;
using Emgu.CV.Structure;
using Emgu.CV.UI;
using Emgu.CV;
using System.Drawing;
using System.Diagnostics;
using System.Windows.Media;
namespace eyeDetection
{
static class Program
{
/// <summary>
/// The main entry point for the application.
/// </summary>
[STAThread]
static void Main()
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Run();
}
static void Run()
{
ImageViewer viewer = new ImageViewer(); //create an image viewer
Capture capture = new Capture(); //create a camera capture
Application.Idle += new EventHandler(delegate(object sender, EventArgs e)
{ // run this until application closed (close button click on image viewer)
Image<Bgr, Byte> image = capture.QueryFrame();
Image<Gray, Byte> gray = image.Convert<Gray, Byte>(); //Convert it to Grayscale
Stopwatch watch = Stopwatch.StartNew();
//normalizes brightness and increases contrast of the image
gray._EqualizeHist();
//Read the HaarCascade objects
HaarCascade eye = new HaarCascade("haarcascade_eye.xml");
MCvAvgComp[][] eyeDetected = gray.DetectHaarCascade(
eye,
1.1,
10,
Emgu.CV.CvEnum.HAAR_DETECTION_TYPE.DO_CANNY_PRUNING,
new Size(20, 20));
foreach (MCvAvgComp e in eyeDetected[0])
{
//draw the eyes detected in the 0th (gray) channel with blue color
image.Draw(e.rect, new Bgr(Color.Blue), 2);
}
watch.Stop();
//display the image
viewer.Image = image; //draw the image obtained from camera
});
viewer.ShowDialog(); //show the image viewer
}
}
}
出於好奇,你是如何做眼動追蹤的?你打開採購這個代碼? –
@Richard看起來他正在使用OpenCV項目的C#綁定:http://www.emgu.com/ – joshperry
@joshperry哦,謝謝。我在編輯它之前沒有看到。 –
