Methods involving maps, imagery, video and steganography
First Claim
1. A method comprising:
- receiving an image from an imager including a digital watermark embedded by a watermark embedder co-located on-chip with the imager, wherein the watermark embedder includes a signal generator and a signal combiner, wherein the watermark embedder further includes a human visual system module, wherein the digital watermark comprises location information;
determining viewing angle specifics of the received image;
decoding the digital watermark to obtain the location information;
identifying a map depicting a location and viewing angle corresponding to the location information and viewing angle specifics, andproviding the map for access over a computer network.

Abstract
The disclosure describes methods and apparatus of providing steganographic indicia or digital watermarking in image or video data. One implementation provides a method of embedding a digital watermark in image data captured by an imager, with watermark embedding occurring on-chip with the imager. Another implementation provides a method of managing images. Each of the images comprises plural-bit data steganographically embedded therein in the form of a digital watermark, with the plural-bit data corresponding to a geo-location. Yet another implementation provides a method of identifying locations on a map, with the map being for display via a computer display. Still another implementation provides a method of introducing a watermark message to a watermark embedder located on-chip with an image array. Other implementations and embodiments are provided as well.
