title: Matlab and ImageJ detecting bone fracture
body: <p>I'm trying to detect a fracture in a picture using imageJ and Matlab, both of them are required. Here is the original image:</p>

  <p>I already established the connection between matlab and imageJ and I've opened the image on imageJ and started by doing some things. First, I used the Find Edges function in imageJ menu to get an outline of the bone. After I did a constrast enhancement to enhance the outline. My problem now is, having only an outline and a black background how can I make an algorithm or something like it that will tell me that the lines don't connect? (meaning there is a fracture in the bone). I did something similar to what is on this video in the part when he ticks the sobel edge detection.</p>
