    Obiektywna metoda upraszczania krzywych a niespójności topologiczne
    (Wydawnictwa AGH, 2005) Żukowska, Maria
    Existing global curve simplifying algorithms, such as Douglas-Peucker algorithm or Chrobak method, despite many advantages, not free from topological inconsistencies are. These point - point, point - line and line - line collisions (where line - line collisions can into selfintersections or intersections of at least two separate curves divided be) could be. There also a problem connected with some elements relative position changing is. Some propositions, that at such inconsistencies solving drive, examined in this paper are. Among them original curve partitioning into segments and star-shaped regions, which would independently simplified be (which selfintersections avoiding enables in turn), and relative position changing investigating with a triangle built of examined segment chord and its relative extremum (like the one in the Chrobak simplifying method used), are.
