The present invention relates to image management systems and methods. In one implementation we provide a method to provide geo-location feedback corresponding to an image area selected by a user. A digital watermark embedded in the selected image area is decoded, and the decoded digital watermark includes or points to geo-location information associated with the selected image location. In another implementation we provide an alert engine to notify a network station that information associated with a digital watermark identifier is available.

Image management system and methods using digital watermarks

The presently claimed invention relates to deriving or extracting information from audio, images and video. One claim recites a method of operating a network filter. The network includes a plurality of network nodes, the network filter is for filtering video or audio. The method includes: monitoring video or audio traffic to a particular network node; identifying a first video or audio at the particular network node through deriving identifying data from data representing the first video or audio, the deriving utilizes at least one programmed multi-purpose computer processor; determining additional information associated with the first video or audio based at least in part on the identifying information; and notifying the network node of the presence of the additional information.

Systems and methods using identifying data derived or extracted from video, audio or images

The present invention relates to systems and methods for managing images or video and related information. In one embodiment, geographic information system (GIS) layer information is registered or aligned to an image or video using digital watermark information embedded within the image or video. Other embodiments are provided as well.

Geographic information systems using digital watermarks

The present invention relates to systems and methods for managing images and related information. In one implementation, geographic information system (GIS) layer information is registered or aligned to an image using digital watermark information embedded within the image.

The present invention provides techniques whereby objects are readily identified. These inventive techniques are ideally suited for traffic monitoring. In one implementation a vehicle is marked with a machine-readable code on an outer, top surface of the vehicle. An elevated or aerial platform captures an image of the vehicle. A detector analyzes the captured image to recover the machine-readable code. The vehicle is identified from such. Traffic congestion can be determined by monitoring the movement of a marked vehicle through the city traffic. In some implementations the machine-readable code comprises an identifier, which is used to interrogate a database for related information.

Marking physical objects and related systems and methods

The present invention provides steganographic-embedding techniques. In one implementation a digital watermark signal is mapped to a set of spatial positions. Physical message objects are positioned according to the set of spatial positions. The signal is provided on a physical structure such as a building or road. The signal may include geo-location information. The geo-location information identifies the location of the physical structure. In other cases the signal includes a marker or identifier. The marker or identifier provides a reference point for images depicting the physical structure.
