تابع HoughLinesBinary خطوط را در تصویر شناسایی می کنه.به صورت زیر:
//Load the image that has been pre-processed
Image<Gray, Byte> cannyGray = new Image<Gray,
byte>(new Bitmap(pictureBox2.Image));
//Call HoughLinesBinary method
LineSegment2D[] lines = cannyGray.HoughLinesBinary(1,
Math.PI / 45.0, 20, 30, 10)[0];
//Draw lines
Image<Bgr, Byte> imageLines = new Image<Bgr,
byte>(cannyGray.Width, cannyGray.Height);
foreach (LineSegment2D line in lines)
{
imageLines.Draw(line, new Bgr(Color.DeepSkyBlue), 5);
}
//Show result
pictureBox2.Image = imageLines.ToBitmap();
