Methods involving maps, imagery, video and steganography

An apparatus comprising:

• an imager configured to capture an image;
• 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;
• a display configured to present the captured image;
• and
• a processor configured to receive the image capture from the imager and embed a digital watermark together with the image into an image file, wherein the watermark embedding occurs on-chip with the imager, wherein the digital watermark comprises location information, wherein the processor is further configured to:
• determine viewing angle specifics of the received image;
• decode the digital watermark in the image tile to obtain the location information;
• identify a map depicting a location and viewing angle corresponding to the location information and viewing angle specifics;
• and
• present the map on the display including the location and the captured image.

A non-transitory computer readable medium having instructions stored thereon, the instructions comprising:

• instructions for 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;
• instructions for determining viewing angle specifics of the received image;
• instructions for decoding the digital watermark to obtain the location information;
• instructions for identifying a map depicting a location and viewing angle corresponding to the location information and viewing angle specifics;
• and
• instructions for providing the map for access over a computer network.
