Dabei wird das Bild vereinfachter dargestellt und bestimmte Grenzen oder Eigenschaften auf dem Bild sind leichter identifizierbar. In diesem Filter wird mit Thresholding, dem Schwellenwertverfahren, gearbeitet. Wie in der folgenden Formel zu erkennen, werden alle Pixel, die eine höhere Intensität als 100 haben, mit einem weißen Pixel der I..."
