Beschreibung

expand_lineexpand_lineExpandLineExpandLineExpandLine erzeugt eine Region durch Expansion, ausgehend von einer Linie (Zeile oder Spalte). Die Expansion wird beendet, sobald der betrachtete Grauwert um mehr als ThresholdThresholdThresholdThresholdthreshold vom Mittelwert entlang der Linie (ExpandTypeExpandTypeExpandTypeExpandTypeexpandType = 'mean'"mean""mean""mean""mean") oder vom zuletzt hinzugefügten Grauwert (ExpandTypeExpandTypeExpandTypeExpandTypeexpandType = 'gradient'"gradient""gradient""gradient""gradient") abweicht.
