Beschreibung

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