Hello Now i got the solution for this by using GrabCutter, First i display live video from webcam(particular person standing front of the fixed background "Grean/Blue"). Then i take one frame from the live video and remove the background by using GrabCutter, but i faced one issue in this solution .i mean, by executing the GrabCutter function it will take long time . In below please check the code, int numberOfIterations = 1; System.Drawing.Rectangle rect = new System.Drawing.Rectangle(0, 10, frame.Width, frame.Height); Image mask = frame.GrabCut(rect, numberOfIterations); while executing this line it will take around 4 minutes... mask = mask.ThresholdBinary(new Gray(2), new Gray(255)); System.Drawing.Color cl = System.Drawing.Color.FromArgb(0, 255, 255, 255); Image processed_image = new Image ("E:\BAR\Back.png"); frame.Copy(processed_image, mask); using (var stream = new MemoryStream()) { // My way to display frame processed_image.Bitmap.Save(stream, ImageFormat.Bmp); BitmapImage bitmap = new BitmapImage(); bitmap.BeginInit(); bitmap.StreamSource = new MemoryStream(stream.ToArray()); bitmap.EndInit(); img1.Source = bitmap; }; Thanks & Regards Vivek A S
