Definition
Diese Klassifikationsstelle umfasst:(Für diese Definition ist die deutsche Übersetzung noch nicht abgeschlossen)
Recognising patterns corresponding to different image structures (e.g., objects) in remotely sensed satellite images or video, e.g. optical data (images or video), GPS, radar, LIDAR measurement data, or in combination.
Object detection, deriving hyperspectral signatures from objects within satellite images.
Categorisation of man-made objects / image targets within satellite images.
Vegetation detection or monitoring canopy growth within satellite images.
Cloud detection and cloud mask segmentation within satellite images.
3D measurement of man-made objects, such as building roofs, within satellite images.
Change detection, e.g. assessing influence of natural disasters, presence of new objects (anomalies) against a known background within satellite images.
Weather condition monitoring by image or video analysis of satellite images.
Examples

Spezielle Klassifizierungsregeln
This group covers techniques specifically adapted for remotely sensed satellite images or video. Recognising patterns in aerial images or video acquired from aircrafts, helicopters, unmanned aerial vehicles (UAVs), balloons, etc., is classified in group G06V 20/17. The difference between these two groups consists how the images are acquired. Image or video techniques classified in group G06V 20/13 lack perspective (depth) information, while in the group group G06V 20/17, images acquired from aircrafts, helicopters, UAVs, etc. contain the perspective (depth) information.
