 to help the user track objects in videos. Each example is provided because it shows how tracktor is able to solve
 various tracking related problems while maintaining individual identities.
 
-### Example 1: Fish Track
+#### Example 1: Fish Track
 This example shows how tracktor is able to track objects in noisy environments. The video shows tracking of a fish
 alone in a tank. A falcon tube is dropped in the tank creating ripples and bubbles in the water. Tracktor is able
 to track the focal fish despite these disturbances.
 
-### Example 2: Spider Track
+#### Example 2: Spider Track
 This example depicts multiple object tracking where objects to be tracked vary considerably in size. The female
 spider is about an order of magnitude (10x) larger than the male spider. In addition to tracking vastly differently
 sized objects simultaneously, this example also shows how individual identity is maintained despite disturbances. At
 00:01:00 into the video, a human enters the frame to examine the web. Despite numerous contours satisfying the tracking
 conditions (seen in the tracked video as contours), tracktor is able to continue tracking focal spiders while
 successfully maintaining their identities.
 
-### Example 3: Termite Track
+#### Example 3: Termite Track
 This example consists of eight termits moving in a petridish. Tracktor is successfully able to track all eight termits
 while maintaining individual identities. In addition to tracking and identifying numerous objects, tracktor is also 
 shown to maintain identity when termites touch each other (during trophallaxis).
