Abstract

Extraktion visueller Merkmale. Basis der Bildähnlichkeitssuche sind die unterschiedlichen visuellen Eigenschaften eines Bildes, seine spezifischen Farb- und Kanteninformationen, welche zunächst in geeigneter Weise erfasst und codiert werden müssen. Dabei kommen sogenannte Deskriptoren zum Einsatz. Die visuelle Information eines Bildes wird in sehr komprimierter Form gespeichert. In unserem Fall hat der zu einem Bild gehörende Deskriptor einen Umfang von nur 96 Byte. Der visuelle Deskriptor codiert sowohl die Farbeigenschaften als auch die spezifischen Kantenmerkmale.
