title: Image Processing - Implementing Sobel Filter
body: <p>I've got a task to implement Sobel filter which is, as you know, an image processing filter for edge detection.
  But unfortunately, I've got no experience in image processing field, to the extent that I don't even know how images are represented in computer. Totally no knowledge in this field.</p>
  
  <p>I've read some papers and PDFs but they focus on many topics which I feel that I may not need them for my task.</p>
  
  <p>I'd be happy to know your suggestions or if there is any particular paper, PDF, tutorial or quick guide for this purpose.</p>
  
  <p>Thank you</p>
  
  <p>EDIT: </p>
  
  <p>Thank you all :)
