Guess what happens when 2 groups of people cross? Stripes. In this paper recently accepted for publication to PlosCB, we explore the formation of stripes in crossing groups of people: stripe detection method, stripe features, dependence on crossing angle, etc. etc.
Everything you’ve wanted to know about stripes but were afraid to ask is here:
