title: Explain Hough Transformation
body: <p>I am just being adventurous and taking my first baby step toward computer vision. I tried to implement the Hough Transformation on my own but I just don't get the whole picture. I read the wikipedia entry, and even the original "use of the hough transformation to detect lines and curves in pictures" by richard Duda and Peter Hart, but didn't help. </p>
  
  <p>Can someone help explaining to me in a more friendly language?</p>
