title: Edge Detection Limitations
body: <p>I am a computer science undergrad trying to come up with a topic for my capstone project.  I am particularly interested in edge detection but I am having troubles coming up with a research area on the topic.  I am looking for some kind of edge detection limitation that is being faced today.</p>
  
  <p>My ideas so far are the following:</p>
  
  <p>Handling edge detection in noisy images - The current method is to use Gaussian smoothing, but we still do not get our desired result.</p>
  
  <p>I have heard a few problems discussing edge detection and the Gestalt Principles.  But I am not finding any good data or research papers on this subtopic.</p>
  
  <p>Does anyone know of any edge detection problems or limitations that still have yet to be solved?  Feel free to elaborate on the two subtopics I mentioned above!</p>
