<p>I have videos of hundreds of people walking from right to left. They're not perfectly in a line, but it's quite sparse enough. I'd like to draw a tag on each of their head and count them. How much of it can be automated? Basically, the method I'm thinking about is something like:</p>
<ol>
<li>Do a face recognition when a person enter the screen.</li>
<li>Put a tag (i.e. draw a physical red rectangle on the head). Step 1 and 2 might have to be done with multiple passes.</li>
<li>Count the tag when a person exit the screen (i.e. count the rectangle).</li>
</ol>
