title: How to do object recognition with OpenCV?
body: <p>I try to make an application which should use the camera in the background (hidden preview) to detect a blinking LED light and count the blinking in a specified time frame (frequency).</p>
  
  <p>However, I searched the net up and down and after a whole day of compiling and troubleshooting the OpenCV integration in my eclipse projects I finally am able to compile running samples of OpenCV without any errors (my PC seems to be a f***ing mess). Now, the samples lack code documentation and I'm still stuck at the very beginning...</p>
  
  <p>Is anybody here at stackoverflow who did work with OpenCV on Android successfully and could give me a hand? Every breadcrumb is a highly welcomed information ;)</p>
  
  <p>Thanks in advance!</p>
