Use the following ToBitmapSource function to convert an IImage (which could be any of Image<TColor, TDepth> class) to a WPF BitmapSource.

using Emgu.CV;
using System.Runtime.InteropServices;

        /// <summary>
        /// Delete a GDI object
        /// </summary>
        /// <param name="o">The poniter to the GDI object to be deleted</param>
        /// <returns></returns>
        private static extern int DeleteObject(IntPtr o);

        /// <summary>
        /// Convert an IImage to a WPF BitmapSource. The result can be used in the Set Property of Image.Source
        /// </summary>
        /// <param name="image">The Emgu CV Image</param>
        /// <returns>The equivalent BitmapSource</returns>
        public static BitmapSource ToBitmapSource(IImage image)
            using (System.Drawing.Bitmap source = image.Bitmap)
                IntPtr ptr = source.GetHbitmap(); //obtain the Hbitmap
                BitmapSource bs = System.Windows.Interop.Imaging.CreateBitmapSourceFromHBitmap(

                DeleteObject(ptr); //release the HBitmap
                return bs;
