Abstract
Depth information may be encoded into pixels of visual imaging data according to steganographic techniques. The depth information may be captured simultaneously with the visual imaging data, and one or more representative pixels may be identified within a region or sector of the visual imaging data according to a pixel traversal strategy. The depth information corresponding to the region or sector may be encoded into one or more least significant bits of the representative pixels, and a modified set of imaging data including the visual imaging data with the depth information encoded into the representative pixels may be stored in a data store and used for any relevant purpose.
