Wolthusen, S.S.WolthusenFunk, W.W.Funk2022-03-082022-03-082006https://publica.fraunhofer.de/handle/publica/307494(A1) Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Markierung von zweidimensionalen georeferenzierten Bilddaten, wobei zumindest ein Bildsegment (1) vorliegt und/oder ermittelt wird, innerhalb des zumindest einen Bildsegments (1) eine Vielzahl von Kacheln (a-i) definiert wird, die jeweils einer Teilfläche des Bildsegments (1) entsprechen, und Bildeigenschaften zumindest eines Teils der Kacheln (a-i) verändert werden und dadurch eine Markierung der Bilddaten vorgenommen wird.DE 102006028376 A1 UPAB: 20080118 NOVELTY - The method involves determining image segments (1,2,3). A Multiple tilings are defined within the image segments, which correspond to a partial area of the image segments. The image characteristics change a part of the tiling and an identification of the image data is carried out. The image segment is defined by a closed circulation outline. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following: (1) a computer program with program code unit (2) a data medium, on which a data structure is stored (3) a computer system, with a data medium (4) a device for identification of two dimensional geo-referenced image data. USE - Used for identification of two dimensional geo-referenced image data (Claimed). ADVANTAGE - The method involves determining image segments. Multiple tilings are defined within the image segments, which correspond to a partial area of the image segments. The image characteristics change a part of the tiling and an identification of the image data is carried out, and hence provide image data with a marking, which is preferably invisible or is not disturbing for the viewer.de006patent102006028376
