Fast 2D model-to-image registration using vanishing points for sports video analysis

This article focuses on the field-to-image registration for TV sports-related image processing through basic geometrical reasoning. We propose a robust automatic line-based method that can cope with imprecisions in the line detection steps through a hypothesis generation/pruning paradigm where the number of hypotheses is reduced by using the vanishing points. The results are satisfying and illustrated with examples from sport.
