HOW TO: Use Image Processing Commands to Improve your Images for Recognition

 String input= @"PATH TO IMAGE";

 using (RasterCodecs codecs = new RasterCodecs())
 {
    try
    {
       // Load a single page of the input file at 24 BPP
       using (RasterImage image = codecs.Load(input, 24, CodecsLoadByteOrder.Rgb, 1, 1))
       {

          // Prepare the command
          DespeckleCommand d_command = new DespeckleCommand();

          // Run command on image to removes speckle
          d_command.Run(image);

         // Prepare the command
          MinumumCommand m_command = new MinumumCommand();

         //Apply the Minimum filter, darkness intensity. 
         command.Dimension = 2;

          // Run command on image to increase darkness intensity on pixels
          m_command.Run(image);

          // Save a single page of the input file after Image Processing at 24 BPP as a RasterPdf
          codecs.Save(image, output, RasterImageFormat.RasPdf, 24);
       }
    }
    catch (Exception ex)
    {
       Console.WriteLine(ex.Message);
    }
