  * The class consists of three basic functions that determine the angle between two lines,
  * the distance between the lines and the common part of the lines. First, all input lines
  * are checked if there is a second line running in the same direction. Thereafter, all line
  * pairs that already fulfilled the angular criterion are checked whether they are close to
  * each other or not, i.e. the orthogonal distance between them is calculated. Finally, it
- * has to be verified if the two lines have a common part since lines may fulfil the two
+ * has to be verified if the two lines have a common part since lines may fulfill the two
  * first criteria but be located in different parts of the image. In order to adapt the
  * detection algorithm to the user’s needs, the thresholds AngularThreshold, DistanceThreshold
  * and CommonDistanceThreshold can be set.
  *
  * A possible processing chain would be to extract lines with a line detector, to convert the
- * result to pathlist objects, to link short line segments with the otbLinkPathListFilter to
- * longer lines and to finally detect all parallel long lines.
