title: How do i use the Emgu CV _SmoothGausian Method
body: <p>Im trying to get the OCR sample app to recognise some small text and how I'm doing it is to resize the image. Once I have resized the image it is all 'pixel-ee'</p>
  
  <p><strong>I want to use the SmothGaussian method to clean it up but I get an error each time I execute the method</strong></p>
  
  <p>Here is the code:</p>
  
  <pre><code>Image&lt;Bgr, Byte&gt; image = new Image&lt;Bgr, byte&gt;(openImageFileDialog.FileName);
  
             using (Image&lt;Gray, byte&gt; gray = image.Convert&lt;Gray, Byte&gt;().Resize(800, 600, Emgu.CV.CvEnum.INTER.CV_INTER_LINEAR, true))
             {
  
                 gray.Convert&lt;Gray, Byte&gt;()._SmoothGaussian(4);
  
  
  
                _ocr.Recognize(gray);
                Tesseract.Charactor[] charactors = _ocr.GetCharactors();
                foreach (Tesseract.Charactor c in charactors)
                {
                    image.Draw(c.Region, drawColor, 1);
                }
  
                imageBox1.Image = image;
  
                //String text = String.Concat( Array.ConvertAll(charactors, delegate(Tesseract.Charactor t) { return t.Text; }) );
                String text = _ocr.GetText();
                ocrTextBox.Text = text;
             }
  </code></pre>
