title: Speeding up Tesseract with OpenCL
body: <p>I have built Tesseract from the source with the option OpenCL enabled in order to speed up the time taken to execute the GetUTF8Text(). I followed these steps:</p>
  
  <pre><code>cd tesseract-3.03/
  ./autogen.sh
  CPPFLAGS="-I/usr/local/include" LDFLAGS="-L/usr/local/lib" ./configure --enable-opencl
  make 
  sudo make install 
  </code></pre>
  
  
  
  <p>However, when I run my code that uses Tesseract, I am not able to experience any speedup in comparison to using Tesseract built without the enabling OpenCL option. 
  Am I missing something here? Am I supposed to make some changes in the Tesseract source? </p>
