Embedding Location Data in Video
First Claim
Patent Images
1. A method comprising:
- obtaining geocoordinates depicting several different geo-locations; and
embedding the geocoordinates in video depicting the several different geo-locations with digital watermarking so that each of the geocoordinates is spatially associated with a video portion that corresponds to the geocorrdinate'"'"'s respective geo-location.

Abstract
Digital watermarking or steganographic data hiding is used to convey location data in video. A digital watermark or steganographic signal may associate geovector or geolocation information with video, video objects or areas depicted in the video. Other implementations and combinations are provided as well.

2. A method comprising:
-
selecting a geo-location;
observing different geo-locations to observe the selected geo-location; and
when the selected geo-location is observed, initiating embedding of digital watermarking in video captured by an airborne platform, the digital watermarking comprising or linking to geocoordinates associated with the selected geo-location.

3. A method of digital watermarking video comprising:
-
steganographically hiding a first, plural-bit payload in data representing a first video portion, the first, plural-bit payload associated with at least one or more ground coordinates associated with the first video portion; and
steganographically hiding a second, plural-bit payload in data representing a second video portion, the second, plural-bit payload associated with a difference between one or more ground coordinates associated with the second video portion and the one or more ground coordinates associated with the first video portion.

4. A method of digital watermarking location data within video captured from an aerial platform comprising:
-
providing a geovector corresponding to a location depicted in at least one frame of the video; and
digital watermarking the geovector in the at least one frame, the digital watermarking hiding the geovector in the at least one frame of the video through alterations to data in the at least one frame of the video, the alterations being generally imperceptible to a human viewer of the video. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11, 12)

- 13. A method to identify video, the video comprising video frames captured from an aerial platform, the aerial platform including at least one of a satellite, helicopter, unmanned aircraft, space shuttle or aircraft, an improvement comprising steganographically embedding data in the video, the data comprising first location data corresponding to at least a first location depicted in the video and second location data corresponding to at least a second location depicted in the video, the first location data differing from the second location data, the steganographic embedding comprising alterations to the video that are generally imperceptible to a human viewer of the video.
