What Does the Average Biker Dude Look Like?

CNN recently published the mugshots of all of the biker gang members who were arrested after the recent shootout in a Waco, TX restaurant. There were a total of 171 pictures, all in the same standard pose and most in the same standard orange jumpsuit:

Seeing all of these pictures got me wondering if it was possible to create an image that represented the typical gang member. I had seen a technique called “pixel averaging” applied to a series of wedding photos many years ago and I was able to find a tool called ImageJ that helped me with the processing.

It was a fairly straightforward effort … just upload the individual photos into an image stack and then apply a z-filter to each pixel of each “slice” or picture in the stack. The result is as follows:

Despite a wide variety of ages, facial hair, and ethnic backgrounds in the mugshots, the combined image looks like some guy you might see at a weekend softball game. It certainly gives no indication of how dangerous some of these men (and women) can be.
