Abstract

Placing object labels in dynamic scenes requires the label positions themselves to be dynamic. Algorithms for dynamic label placement are presented that tend to avoid overlaps and consider aesthetic preferences. The procedures are derived from a quadratic program. As a special feature, hysteresis is incorporated to restrict the optical flow induced by label changes.
