  Hi,

  Sometimes source images may need to be preprocessed before recognition, and FREngine allows to do it by using different methods of the ImageDocument object. For example, you can use the ImageDocument::RemoveMotionBlur method to remove motion blur from the specified region of the image. The method is primarily designed for preprocessing the images obtained by a digital camera. The usage code snippet may be the following:

  ...
  // Create document
  FREngine.FRDocument document = engineLoader.Engine.CreateFRDocument();
  
  try {
    // Add image file to document
    displayMessage( "Loading image..." );
    document.AddImageFile( imagePath, null, null );
   
    // Add image file to document
    document.AddImageFile(imagePath, null, null);
  
    int pagesCount = document.Pages.Count;
    for (int i = 0; i < pagesCount; i++)
       {
          FREngine.FRPage page = document.Pages.Item( i );
          page.ImageDocument.RemoveMotionBlur( null );
       }
    ...
