Evaluation of Penalty Functions for Semi-global Matching Cost Aggregation

  title={Evaluation of Penalty Functions for Semi-global Matching Cost Aggregation},
  author={Christian Banz and Peter Pirsch and Holger Blume},
The stereo matching method semi-global matching (SGM) relies on consistency constraints during the cost aggregation which are enforced by so-called penalty terms. This paper proposes new and evaluates four penalty functions for SGM. Due to mutual dependencies, two types of matching cost calculation, census and rank transform, are considered. Performance is measured using original and degenerated images exhibiting radiometric changes and noise from the Middlebury benchmark. The two best… CONTINUE READING
