emgucv

If you are familiar with OpenCV library, you know what Haar Cascade image object detection is. By image object detection I mean, like human face detection or something else. I have some Haar Cascade XMLs for face detection, but I don't know how to create my own. I want to create Haar Cascade XMLs to detect simple bright circle light sources (i.e. flashing infrared light from TV remote control). So, how do I create a Haar Cascade (.xml file) to use in OpenCV? I think this might be helpful: http://note.sonots.com/SciSoftware/haartraining.html This might be helpful http://opencvuser.blogspot.in

i really a newbie with EgmuCV i try to capture images from webcam with the following code: //Program.cs (Winform) using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Windows.Forms; using Emgu.CV; using Emgu.CV.UI; using Emgu.Util; using Emgu.CV.Structure; namespace EgmuCVTest { public partial class Form1 : Form { public Form1() { InitializeComponent(); } private void button1_Click(object sender, EventArgs e) { Capture cp = new Capture(); ImageViewer imv = new ImageViewer();

I'm getting this error The type initializer for 'Emgu.CV.CvInvoke' threw an exception. when I try to use Emgu CV. I've tried everything I can think of to fix this but it's still giving the same error, and when I click a button it shows Object reference not set to an instance of an object. This is the code I'm trying: void ProcessFunction(object sender, EventArgs e) { imgOrg = capturecam.QueryFrame(); if (imgOrg == null) return; imgProc = imgOrg.InRange(new Bgr(50, 50, 50), new Bgr(255, 255, 255)); imgProc = imgProc.SmoothGaussian(9); imageBox1.Image = imgOrg; imageBox2.Image = imgProc; } What
