But only works if parameterizations of curves correspond to each other! Instead of Euclidean distance use the radius of the minimum enclosing disk for k points. Tries out all joint reparameterizations of curves.
Dumitrescu, G. Har-Peled, B. Median The average is allowed to introduce new vertices and curve pieces. Can one compute a median, which uses only existing curve pieces and which is central with respect to number of trajectories? Average trajectory would go through lake. Silveira, C. Wenk, L. Simple median: Switch trajectory at every intersection. If all input trajectories are homotopic w.

The distance measures generally work for undirected or directed embedded graph models , and they include partial distances that match the constructed graph to a subset of the ground-truth.
The general approaches include point set-based distances, path-based distances , and distances that compare the local topology of the graphs. In addition to distance measures, the concept of local distance signatures is introduced in order to visualize local differences and to locate the cause of large distances. Although a visual inspection allows for a simple intuitive assessment of map construction results, providing a quantifiable assessment of the quality has been a considerable challenge. This chapter summarizes the results of a study that compares three map construction algorithms for three different datasets and using four quality measures.

The results illustrate the strengths and limitations of the algorithms representing three distinct categories of map construction approaches. Map construction algorithms are useful beyond GPS-derived trajectory datasets. This chapter gives some examples of early-stage research towards novel applications. In recent years an ever increasing amount of social media data has become available.
The result is used to study different optical representation concepts, such as distractions, content layout, and usability. This chapter introduces resources that complement the scientific discussion of map construction algorithms and provide the interested researcher with the simplest possible means to start experimenting with map construction algorithms.
