Hello!
A good guide to capturing video using the aforge.net library:

Just need to repeat everything after this guy.
Aforge is a good library, you can also use emgu.cv.

thanks u !
ex : i will capture image form picturebox1 to picturebox4(show image captured) ?
How to start template matching at picturebox 4 ?

` if (minValFirst <= minVal1 & maxValFirst >= maxVal1 & maxValFirst0 >= maxValValid)
{
CvInvoke.Rectangle(source, rect, new MCvScalar(0, 255, 0), 3);
CvInvoke.DrawMarker(source, new Point(centerX, centerY), new MCvScalar(0, 255, 0), MarkerTypes.Diamond);
pictureBox4.Image = source.AsBitmap();
myQueueCountOK.Enqueue(count);
myQueueXOK.Enqueue(centerX);
myQueueYOK.Enqueue(centerY);

                    if (myQueueCountOK.Count > numberCount)
                    {
                        myQueueCountOK.Dequeue();
                        myQueueXOK.Dequeue();
                        myQueueYOK.Dequeue();

                        arrayCountOK = myQueueCountOK.ToArray();
                        arrayXOK = myQueueXOK.ToArray();
                        arrayYOK = myQueueYOK.ToArray();
                        BeginInvoke(new Action(() => { result.Text = "OK"; }));
                    }
                    else
                    {
                        arrayCountOK = myQueueCountOK.ToArray();
                        arrayXOK = myQueueXOK.ToArray();
                        arrayYOK = myQueueYOK.ToArray();
                    }
                    for (int i = 0; i < arrayCountOK.Length; i++)
                    {
                        CvInvoke.DrawMarker(source, new Point(arrayXOK[i], arrayYOK[i]), new MCvScalar(0, 255, 0), MarkerTypes.Cross, 4, 1);


                    }

                }`

convert Image type to Image<Bgr, Byte>
for example:
var template = new Bitmap(pictureBox4.Image).ToImage<Bgr, byte>();
