Abstract: In some examples, an article of conspicuity tape includes a retroreflective substrate; and a structured texture element (STE) embodied on the retroreflective substrate, wherein a visual appearance of the structured texture element is computationally generated for differentiation from a visual appearance of a natural environment scene for the article of conspicuity tape.
