I have difficulty when convert mat to bitmap image and display on image object in C# WPF

private void Generate_btn_Click(object sender, RoutedEventArgs e)
        {
            Brisk detector = new Brisk();
            WarperCreator warper = new SphericalWarper();

            Stitcher stitcher = new Stitcher();
            stitcher.SetFeaturesFinder(detector);
            stitcher.SetWarper(warper);
            Mat outputImage = new Mat();
            var status = stitcher.Stitch(imagesList, outputImage);
            if (status == Stitcher.Status.Ok)
            {
                BitmapImage img = outputImage.ToBitmap();
                Result_img.Source = logo;

            }
        }
